numid
This crate provide the numid!
macro for generating structures which behave like numerical id.
Example
use numid::numid;
numid!(pub 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);
}
Usage
Add this to your Cargo.toml
:
[dependencies]
numid = "0.2"
You can now create all the ids you want in your programs :
use numid::numid;
numid!(struct Id); numid!(pub struct Id2); numid!(pub(crate) struct Id3); numid!(#[doc(hidden)] struct Id4); numid!(struct Id5 -> 100); numid!(struct Id6(u128)); numid!(@CloneIsReproduce struct Id7); numid!(#[doc(hidden)] @CloneIsNew pub struct Id8(u32) -> 10);
