uniqify

A Rust equivalent of the C macro __COUNTER__, generating unique integers at compile time.

Features

• Generates unique and deterministic usize at each call
• Works at comptime thanks to a procedural macro
• Not 100% safe (has not been widely tested and debugged) but simple to use shrug

Installation

cargo add uniqify

Usage

use uniqify::uniqify;

fn main() {
    let a = uniqify!();
    let b = uniqify!();
    let c = uniqify!();

    println!("{a}, {b}, {c}");
}

Expected result

0, 1, 2

Notes

If there are any issues, I will try to resolve them, but I must admit that I am not very good with macros and that, for me, it is still a bit of a miracle.
