Macro breadthread::key_type

macro_rules! key_type {
    ($(#[$meta : meta]) * $vis : vis struct $tyname : ident($foreign : ident) :
 [$traitname : ident, $value : expr] ;) => { ... };
}

Create a type that internally wraps around Key.

Example

use breadthread::Key;
use std::num::NonZeroUsize;

pub struct ForeignPointerType { no_data: [u8; 0] }

breadthread::key_type! {
    /// Foobar.
    pub struct MyType(ForeignPointerType) : [ForeignType, 0x1337];
}

let key = MyType::from_raw(NonZeroUsize::new(0x12).unwrap());
assert_eq!(key.into_raw(), NonZeroUsize::new(0x12).unwrap());
let _inner_key: Key<ForeignType> = key.into_key();
assert_eq!(key.identifier(), 0x1337);

Note

The new type already derives Debug, Copy, Clone, PartialOrd, Ord, PartialEq, Eq, and Hash. Deriving these yourself will likely result in an error.
