hyperid-rs

Superfast id generator

This is a porting of the amazing hyperid project written in javascript.

Install

Add the dependency to your Cargo.toml:

[dependencies]
hyperid = "2"

Usage

use hyperid::HyperId;

fn main() {
    let mut hyperid = HyperId::default();

    // `generate` method returns a new id every time
    let id1 = hyperid.generate();
    let id2 = hyperid.generate();

    assert_ne!(id1, id2);

    // `get` method returns the last generated id
    let id3 = hyperid.get();

    assert_eq!(id2, id3);

    // Only if `url_safe` feature is enabled
    println!("{}", id1.to_url_safe()); // prints "3ZAYYJilG7vHTqiUuaQdFg.0"
}

test uuid    ... bench:       1,657 ns/iter (+/- 148)
...
