 </span><span class="doccomment">//! 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 `struct`s that manage a set of flags. The
 //! flags should only be defined for integer types, otherwise unexpected type
 //! errors may occur at compile time.
 //!
 //! # Example
 //!
 //! ```
 //! use bitflags::bitflags;
 //!
 //! bitflags! {
 //!     struct Flags: u32 {
 //!         const A = 0b00000001;
 //!         const B = 0b00000010;
 //!         const C = 0b00000100;
 //!         const ABC = Self::A.bits | Self::B.bits | Self::C.bits;
 //!     }
 //! }
 //!
 //! fn main() {
 //!     let e1 = Flags::A | Flags::C;
 //!     let e2 = Flags::B | Flags::C;
 //!     assert_eq!((e1 | e2), Flags::ABC);   // union
 //!     assert_eq!((e1 &amp; e2), Flags::C);     // intersection
 //!     assert_eq!((e1 - e2), Flags::A);     // set difference
 //!     assert_eq!(!e2, Flags::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:
 //!
 //! ```
 //! use std::fmt;
 //!
 //! use bitflags::bitflags;
 //!
 //! bitflags! {
 //!     struct Flags: u32 {
 //!         const A = 0b00000001;
 //!         const B = 0b00000010;
 //!     }
 //! }
 //!
 //! impl Flags {
 //!     pub fn clear(&amp;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(&amp;self, f: &amp;mut fmt::Formatter) -&gt; fmt::Result {
 //!         write!(f, &quot;hi!&quot;)
 //!     }
 //! }
 //!
 //! fn main() {
 //!     let mut flags = Flags::A | Flags::B;
 //!     flags.clear();
 //!     assert!(flags.is_empty());
 //!     assert_eq!(format!(&quot;{}&quot;, flags), &quot;hi!&quot;);
 //!     assert_eq!(format!(&quot;{:?}&quot;, Flags::A | Flags::B), &quot;A | B&quot;);
 //!     assert_eq!(format!(&quot;{:?}&quot;, Flags::B), &quot;B&quot;);
 //! }
 //! ```
 //!
 //! # Visibility
 //!
 //! The generated structs and their 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 `struct`:
 //!
 //! ```
 //! mod example {
 //!     use bitflags::bitflags;
 //!
 //!     bitflags! {
 //!         pub struct Flags1: u32 {
 //!             const A = 0b00000001;
 //!         }
 //!
 //! #       pub
 //!         struct Flags2: u32 {
 //!             const B = 0b00000010;
 //!         }
 //!     }
 //! }
 //!
 //! fn main() {
 //!     let flag1 = example::Flags1::A;
 //!     let flag2 = example::Flags2::B; // error: const `B` is private
 //! }
 //! ```
 //!
 //! # Attributes
 //!
 //! Attributes can be attached to the generated `struct`s by placing them
 //! before the `struct` keyword.
 //!
 //! ## Representations
 //!
 //! It&#39;s valid to add a `#[repr(C)]` or `#[repr(transparent)]` attribute to a type
 //! generated by `bitflags!`. In these cases, the type is guaranteed to be a newtype.
 //!
 //! ```
 //! use bitflags::bitflags;
 //!
 //! bitflags! {
 //!     #[repr(transparent)]
 //!     struct Flags: u32 {
 //!         const A = 0b00000001;
 //!         const B = 0b00000010;
 //!         const C = 0b00000100;
 //!     }
 //! }
 //! ```
 //!
 //! # Trait implementations
 //!
 //! The `Copy`, `Clone`, `PartialEq`, `Eq`, `PartialOrd`, `Ord` and `Hash`
 //! traits are automatically derived for the `struct`s using the `derive` attribute.
 //! Additional traits can be derived by providing an explicit `derive`
 //! attribute on `struct`.
 //!
 //! The `Extend` and `FromIterator` traits are implemented for the `struct`s,
 //! too: `Extend` adds the union of the instances of the `struct` iterated over,
 //! while `FromIterator` calculates the union.
 //!
 //! The `Binary`, `Debug`, `LowerHex`, `Octal` and `UpperHex` traits are also
 //! implemented by displaying the bits value of the internal struct.
 //!
 //! ## Operators
 //!
 //! The following operator traits are implemented for the generated `struct`s:
 //!
 //! - `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`s:
 //!
 //! - `empty`: an empty set of flags
 //! - `all`: the set of all defined 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
 //!                defined flag
 //! - `from_bits_truncate`: convert from underlying bit representation, dropping
 //!                         any bits that do not correspond to defined flags
 //! - `from_bits_unchecked`: convert from underlying bit representation, keeping
 //!                          all bits (even those not corresponding to defined
 //!                          flags)
 //! - `is_empty`: `true` if no flags are currently stored
 //! - `is_all`: `true` if currently set flags exactly equal all defined flags
 //! - `intersects`: `true` if there are flags common to both `self` and `other`
 //! - `contains`: `true` if 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.
 //! - `set`: inserts or removes the specified flags depending on the passed value
 //! - `intersection`: returns a new set of flags, containing only the flags present
 //!                   in both `self` and `other` (the argument to the function).
 //! - `union`: returns a new set of flags, containing any flags present in
 //!            either `self` or `other` (the argument to the function).
 //! - `difference`: returns a new set of flags, containing all flags present in
 //!                 `self` without any of the flags present in `other` (the
 //!                 argument to the function).
 //! - `symmetric_difference`: returns a new set of flags, containing all flags
 //!                           present in either `self` or `other` (the argument
 //!                           to the function), but not both.
 //! - `complement`: returns a new set of flags, containing all flags which are
 //!                 not set in `self`, but which are allowed for this type.
 //!
 //! ## Default
 //!
 //! The `Default` trait is not automatically implemented for the generated structs.
 //!
 //! 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`:
 //!
 //! ```
 //! use bitflags::bitflags;
 //!
 //! bitflags! {
 //!     // Results in default value with bits: 0
 //!     #[derive(Default)]
 //!     struct Flags: u32 {
 //!         const A = 0b00000001;
 //!         const B = 0b00000010;
 //!         const 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:
 //!
 //! ```
 //! use bitflags::bitflags;
 //!
 //! bitflags! {
 //!     struct Flags: u32 {
 //!         const A = 0b00000001;
 //!         const B = 0b00000010;
 //!         const C = 0b00000100;
 //!     }
 //! }
 //!
 //! // explicit `Default` implementation
 //! impl Default for Flags {
 //!     fn default() -&gt; Flags {
 //!         Flags::A | Flags::C
 //!     }
 //! }
 //!
 //! fn main() {
 //!     let implemented_default: Flags = Default::default();
 //!     assert_eq!(implemented_default, (Flags::A | Flags::C));
 //! }
 //! ```
 //!
 //! # Zero Flags
 //!
 //! Flags with a value equal to zero will have some strange behavior that one should be aware of.
 //!
 //! ```
 //! use bitflags::bitflags;
 //!
 //! bitflags! {
 //!     struct Flags: u32 {
 //!         const NONE = 0b00000000;
 //!         const SOME = 0b00000001;
 //!     }
 //! }
 //!
 //! fn main() {
 //!     let empty = Flags::empty();
 //!     let none = Flags::NONE;
 //!     let some = Flags::SOME;
 //!
 //!     // Zero flags are treated as always present
 //!     assert!(empty.contains(Flags::NONE));
 //!     assert!(none.contains(Flags::NONE));
 //!     assert!(some.contains(Flags::NONE));
 //!
 //!     // Zero flags will be ignored when testing for emptiness
 //!     assert!(none.is_empty());
 //! }
 //! ```
 //!
 //! Users should generally avoid defining a flag with a value of zero.
