+
+   "Work" shall mean the work of authorship, whether in Source or
+   Object form, made available under the License, as indicated by a
+   copyright notice that is included in or attached to the work
+   (an example is provided in the Appendix below).
+
+   "Derivative Works" shall mean any work, whether in Source or Object
+   form, that is based on (or derived from) the Work and for which the
+   editorial revisions, annotations, elaborations, or other modifications
+   represent, as a whole, an original work of authorship. For the purposes
+   of this License, Derivative Works shall not include works that remain
+   separable from, or merely link (or bind by name) to the interfaces of,

+
+   "Contributor" shall mean Licensor and any individual or Legal Entity
+   on behalf of whom a Contribution has been received by Licensor and
+   subsequently incorporated within the Work.
+
+2. Grant of Copyright License. Subject to the terms and conditions of
+   this License, each Contributor hereby grants to You a perpetual,
+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,
+   publicly display, publicly perform, sublicense, and distribute the
+   Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of

+   (except as stated in this section) patent license to make, have made,
+   use, offer to sell, sell, import, and otherwise transfer the Work,

+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+

+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or

+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       attribution notices from the Source form of the Work,
+       excluding those notices that do not pertain to any part of
+       the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside

+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.

+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each

+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the

+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf

+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+/// The `bitflags!` macro generates a `struct` that holds a set of C-style
+/// bitmask flags. It is useful for creating typesafe wrappers for C APIs.
+///
+/// The flags should only be defined for integer types, otherwise unexpected
+/// type errors may occur at compile time.
+///
+/// # Example
+///
+/// ```{.rust}
+/// #[macro_use]
+/// extern crate bitflags;
+///
+/// bitflags! {
+///     flags Flags: u32 {
+///         const FLAG_A       = 0b00000001,
+///         const FLAG_B       = 0b00000010,
+///         const FLAG_C       = 0b00000100,
+///         const FLAG_ABC     = FLAG_A.bits
+///                            | FLAG_B.bits
+///                            | FLAG_C.bits,
+///     }
+/// }
+///
+/// fn main() {
+///     let e1 = FLAG_A | FLAG_C;
+///     let e2 = FLAG_B | FLAG_C;
+///     assert_eq!((e1 | e2), FLAG_ABC);   // union
+///     assert_eq!((e1 & e2), FLAG_C);     // intersection
+///     assert_eq!((e1 - e2), FLAG_A);     // set difference
+///     assert_eq!(!e2, FLAG_A);           // set complement
+/// }
+/// ```
+///
+/// The generated `struct`s can also be extended with type and trait
+/// implementations:
+///
+/// ```{.rust}
+/// #[macro_use]
+/// extern crate bitflags;
+///
+/// use std::fmt;
+///
+/// bitflags! {
+///     flags Flags: u32 {
+///         const FLAG_A   = 0b00000001,
+///         const FLAG_B   = 0b00000010,
+///     }
+/// }
+///
+/// impl Flags {
+///     pub fn clear(&mut self) {
+///         self.bits = 0;  // The `bits` field can be accessed from within the
+///                         // same module where the `bitflags!` macro was invoked.
+///     }
+/// }
+///
+/// impl fmt::Display for Flags {
+///     fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
+///         write!(f, "hi!")
+///     }
+/// }
+///
+/// fn main() {
+///     let mut flags = FLAG_A | FLAG_B;
+///     flags.clear();
+///     assert!(flags.is_empty());
+///     assert_eq!(format!("{}", flags), "hi!");
+///     assert_eq!(format!("{:?}", FLAG_A | FLAG_B), "FLAG_A | FLAG_B");
+///     assert_eq!(format!("{:?}", FLAG_B), "FLAG_B");
+/// }
+/// ```
+///
+/// # Visibility
+///
+/// The generated struct and its associated flag constants are not exported
+/// out of the current module by default. A definition can be exported out of
+/// the current module by adding `pub` before `flags`:
+///
+/// ```{.rust},ignore
+/// #[macro_use]
+/// extern crate bitflags;
+///
+/// mod example {
+///     bitflags! {
+///         pub flags Flags1: u32 {
+///             const FLAG_A   = 0b00000001,
+///         }
+///     }
+///     bitflags! {
+///         flags Flags2: u32 {
+///             const FLAG_B   = 0b00000010,
+///         }
+///     }
+/// }
+///
+/// fn main() {
+///     let flag1 = example::FLAG_A;
+///     let flag2 = example::FLAG_B; // error: const `FLAG_B` is private

+///
+/// # Attributes
+///
+/// Attributes can be attached to the generated `struct` by placing them
+/// before the `flags` keyword.
+///
+/// # Trait implementations
+///
+/// The `Copy`, `Clone`, `PartialEq`, `Eq`, `PartialOrd`, `Ord` and `Hash`
+/// traits automatically derived for the `struct` using the `derive` attribute.
+/// Additional traits can be derived by providing an explicit `derive`
+/// attribute on `flags`.
+///
+/// The `Extend` and `FromIterator` traits are implemented for the `struct`,
+/// too: `Extend` adds the union of the instances of the `struct` iterated over,
+/// while `FromIterator` calculates the union.
+///
+/// The `Debug` trait is also implemented by displaying the bits value of the
+/// internal struct.
+///
+/// ## Operators
+///
+/// The following operator traits are implemented for the generated `struct`:
+///
+/// - `BitOr` and `BitOrAssign`: union
+/// - `BitAnd` and `BitAndAssign`: intersection
+/// - `BitXor` and `BitXorAssign`: toggle
+/// - `Sub` and `SubAssign`: set difference
+/// - `Not`: set complement
+///
+/// As long as the assignment operators are unstable rust feature they are only
+/// available with the crate feature `assignment_ops` enabled.
+///
+/// # Methods
+///
+/// The following methods are defined for the generated `struct`:
+///
+/// - `empty`: an empty set of flags
+/// - `all`: the set of all flags
+/// - `bits`: the raw value of the flags currently stored
+/// - `from_bits`: convert from underlying bit representation, unless that
+///                representation contains bits that do not correspond to a flag
+/// - `from_bits_truncate`: convert from underlying bit representation, dropping
+///                         any bits that do not correspond to flags
+/// - `is_empty`: `true` if no flags are currently stored
+/// - `is_all`: `true` if all flags are currently set
+/// - `intersects`: `true` if there are flags common to both `self` and `other`
+/// - `contains`: `true` all of the flags in `other` are contained within `self`
+/// - `insert`: inserts the specified flags in-place
+/// - `remove`: removes the specified flags in-place
+/// - `toggle`: the specified flags will be inserted if not present, and removed
+///             if they are.

-//! A typesafe bitmask flag generator.
+//! A typesafe bitmask flag generator useful for sets of C-style bitmask flags.
+//! It can be used for creating typesafe wrappers around C APIs.
+//!
+//! The `bitflags!` macro generates a `struct` that manages a set of flags. The
+//! flags should only be defined for integer types, otherwise unexpected type
+//! errors may occur at compile time.
+//!
+//! # Example
+//!
+//! ```
+//! #[macro_use]
+//! extern crate bitflags;
+//!
+//! bitflags! {
+//!     struct Flags: u32 {
+//!         const FLAG_A       = 0b00000001;
+//!         const FLAG_B       = 0b00000010;
+//!         const FLAG_C       = 0b00000100;
+//!         const FLAG_ABC     = FLAG_A.bits
+//!                            | FLAG_B.bits
+//!                            | FLAG_C.bits;
+//!     }
+//! }
+//!
+//! fn main() {
+//!     let e1 = FLAG_A | FLAG_C;
+//!     let e2 = FLAG_B | FLAG_C;
+//!     assert_eq!((e1 | e2), FLAG_ABC);   // union
+//!     assert_eq!((e1 & e2), FLAG_C);     // intersection
+//!     assert_eq!((e1 - e2), FLAG_A);     // set difference
+//!     assert_eq!(!e2, FLAG_A);           // set complement
+//! }
+//! ```
+//!
+//! See [`example_generated::Flags`](./example_generated/struct.Flags.html) for documentation of code
+//! generated by the above `bitflags!` expansion.
+//!
+//! The generated `struct`s can also be extended with type and trait
+//! implementations:
+//!
+//! ```
+//! #[macro_use]
+//! extern crate bitflags;
+//!
+//! use std::fmt;
+//!
+//! bitflags! {
+//!     struct Flags: u32 {
+//!         const FLAG_A   = 0b00000001;
+//!         const FLAG_B   = 0b00000010;
+//!     }
+//! }
+//!
+//! impl Flags {
+//!     pub fn clear(&mut self) {
+//!         self.bits = 0;  // The `bits` field can be accessed from within the
+//!                         // same module where the `bitflags!` macro was invoked.
+//!     }
+//! }
+//!
+//! impl fmt::Display for Flags {
+//!     fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
+//!         write!(f, "hi!")
+//!     }
+//! }
+//!
+//! fn main() {
+//!     let mut flags = FLAG_A | FLAG_B;
+//!     flags.clear();
+//!     assert!(flags.is_empty());
+//!     assert_eq!(format!("{}", flags), "hi!");
+//!     assert_eq!(format!("{:?}", FLAG_A | FLAG_B), "FLAG_A | FLAG_B");
+//!     assert_eq!(format!("{:?}", FLAG_B), "FLAG_B");
+//! }
+//! ```
+//!
+//! # Visibility
+//!
+//! The generated struct and its associated flag constants are not exported
+//! out of the current module by default. A definition can be exported out of
+//! the current module by adding `pub` before `flags`:
+//!
+//! ```ignore
+//! #[macro_use]
+//! extern crate bitflags;
+//!
+//! mod example {
+//!     bitflags! {
+//!         pub struct Flags1: u32 {
+//!             const FLAG_A   = 0b00000001;
+//!         }
+//!     }
+//!     bitflags! {
+//!         struct Flags2: u32 {
+//!             const FLAG_B   = 0b00000010;
+//!         }
+//!     }
+//! }
+//!
+//! fn main() {
+//!     let flag1 = example::FLAG_A;
+//!     let flag2 = example::FLAG_B; // error: const `FLAG_B` is private
+//! }
+//! ```
+//!
+//! # Attributes
+//!
+//! Attributes can be attached to the generated `struct` by placing them
+//! before the `flags` keyword.
+//!
+//! # Trait implementations
+//!
+//! The `Copy`, `Clone`, `PartialEq`, `Eq`, `PartialOrd`, `Ord` and `Hash`
+//! traits automatically derived for the `struct` using the `derive` attribute.
+//! Additional traits can be derived by providing an explicit `derive`
+//! attribute on `flags`.
+//!
+//! The `Extend` and `FromIterator` traits are implemented for the `struct`,
+//! too: `Extend` adds the union of the instances of the `struct` iterated over,
+//! while `FromIterator` calculates the union.
+//!
+//! The `Binary`, `Debug`, `LowerExp`, `Octal` and `UpperExp` trait is also
+//! implemented by displaying the bits value of the internal struct.
+//!
+//! ## Operators
+//!
+//! The following operator traits are implemented for the generated `struct`:
+//!
+//! - `BitOr` and `BitOrAssign`: union
+//! - `BitAnd` and `BitAndAssign`: intersection
+//! - `BitXor` and `BitXorAssign`: toggle
+//! - `Sub` and `SubAssign`: set difference
+//! - `Not`: set complement
+//!
+//! # Methods
+//!
+//! The following methods are defined for the generated `struct`:
+//!
+//! - `empty`: an empty set of flags
+//! - `all`: the set of all flags
+//! - `bits`: the raw value of the flags currently stored
+//! - `from_bits`: convert from underlying bit representation, unless that
+//!                representation contains bits that do not correspond to a flag
+//! - `from_bits_truncate`: convert from underlying bit representation, dropping
+//!                         any bits that do not correspond to flags
+//! - `is_empty`: `true` if no flags are currently stored
+//! - `is_all`: `true` if all flags are currently set
+//! - `intersects`: `true` if there are flags common to both `self` and `other`
+//! - `contains`: `true` all of the flags in `other` are contained within `self`
+//! - `insert`: inserts the specified flags in-place
+//! - `remove`: removes the specified flags in-place
+//! - `toggle`: the specified flags will be inserted if not present, and removed
+//!             if they are.
+//!
+//! ## Default
+//!
+//! The `Default` trait is not automatically implemented for the generated struct.
+//!
+//! If your default value is equal to `0` (which is the same value as calling `empty()`
+//! on the generated struct), you can simply derive `Default`:
+//!
+//! ```
+//! #[macro_use]
+//! extern crate bitflags;
+//!
+//! bitflags! {
+//!     // Results in default value with bits: 0
+//!     #[derive(Default)]
+//!     struct Flags: u32 {
+//!         const FLAG_A       = 0b00000001;
+//!         const FLAG_B       = 0b00000010;
+//!         const FLAG_C       = 0b00000100;
+//!     }
+//! }
+//!
+//! fn main() {
+//!     let derived_default: Flags = Default::default();
+//!     assert_eq!(derived_default.bits(), 0);
+//! }
+//! ```
+//!
+//! If your default value is not equal to `0` you need to implement `Default` yourself:
+//!
+//! ```
+//! #[macro_use]
+//! extern crate bitflags;
+//!
+//! bitflags! {
+//!     struct Flags: u32 {
+//!         const FLAG_A       = 0b00000001;
+//!         const FLAG_B       = 0b00000010;
+//!         const FLAG_C       = 0b00000100;
+//!     }
+//! }
+//!
+//! // explicit `Default` implementation
+//! impl Default for Flags {
+//!     fn default() -> Flags {
+//!         FLAG_A | FLAG_C
+//!     }
+//! }
+//!
+//! fn main() {
+//!     let implemented_default: Flags = Default::default();
+//!     assert_eq!(implemented_default, (FLAG_A | FLAG_C));
+//! }
+//! ```
