[−][src]Crate numid
This crate provide the numid!
macro for creating numerical id.
Syntax
ⓘThis example is not tested
numid!([pub] struct NAME [(TYPE)] [-> CONSTANT]);
If not indicated, TYPE=u64
and CONSTANT=0
.
Attributes
Attributes can be attached to the generated struct
by placing them
before the struct
keyword (or pub
if public).
Exemples
numid!(struct MyId -> 10); fn main() { let id1 = MyId::new(); let id2 = MyId::new(); assert!(id2 > id1); assert_eq!(id1.value(), 11); assert_eq!(id2.value(), 12); }
Trait implementations
The Copy
, Clone
, PartialEq
, Eq
, PartialOrd
, Ord
, Hash
and Debug
traits automatically derived for the struct
using the derive
attribute.
Additional traits can be derived by providing an explicit derive
attribute.
The Display
and Default
traits are implemented for the struct
. When
calling default()
, the struct is initialied with a new value instead of 0
.
