-//! 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 & 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(&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 = Flags::A | Flags::B;
-//!     flags.clear();
-//!     assert!(flags.is_empty());
-//!     assert_eq!(format!("{}", flags), "hi!");
-//!     assert_eq!(format!("{:?}", Flags::A | Flags::B), "A | B");
-//!     assert_eq!(format!("{:?}", Flags::B), "B");
-//! }
-//! ```
-//!
-//! # 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'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() -> 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.
