This crate provide the numid! macro for generating structures which behave like numerical id.
```rust 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);
} ```
Add this to your Cargo.toml :
toml
[dependencies]
numid = "0.2"
You can now create all the ids you want in your programs :
```rust use numid::numid;
numid!(struct Id); // basic id numid!(pub struct Id2); // public numid!(pub(crate) struct Id3); // restricted public numid!(#[doc(hidden)] struct Id4); // with attribut numid!(struct Id5 -> 100); // init const specified numid!(struct Id6(u128)); // type specified numid!(#[doc(hidden)] pub struct Id7(u32) -> 10); // all the thing you can want ``` Consult the documentation for more information.
