numid

This crate provide the numid! macro for generating structures which behave like numerical id.

Example

```rust

#[macro_use]

extern crate 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:

toml [dependencies] numid = "0.1.2"

and this to your crate root:

```rust

[macro_use]

extern crate numid; ```

Features

This crate can be used without the standard library (#![no_std]) by disabling the default std feature. The only functionnality disabled if std is disabled is the implementation of the Display trait.
