yauuid

The uuid crate generates and parse UUIDs based on RFC 4122 and DCE 1.1: Authentication and Security Services.

Documentation

Usage

Add this to your Cargo.toml:

[denpendencies]
yauuid = "0.2"

and this to your crate root:

extern crate yauuid;

Examples

To parse a simple UUID, then print the version and variant:

extern crate yauuid;

use yauuid::Uuid;
use std::str::FromStr;

fn main() {
    let u = Uuid::from_str("urn:uuid:123e4567-e89b-12d3-a456-426655440000").unwrap();
    println!("version = {}, variant = {}", u.version(), u.variant());
}

The library supports 5 versions of UUID:

Benchmarks

Lower is better.

The parse_str benchmark is 2x, and to_string is 1.5x.

The new_v1 costs are similar, but yauuid's version is easy to use. No time parameters required. It has been included in yauuid::Context struct.

The new_v3, new_v4, new_v5 benchmark md5, RNG, sha1 performance instead.

Run cargo bench to get the benchmark result.

See benches/bench.rs for benchmark cases detail.
