yauuid
The uuid crate generates and parse UUIDs based on RFC 4122 and DCE 1.1: Authentication and Security Services.
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:
Name | Version |
---|---|
Mac | Version 1: Mac address |
Dce | Version 2: DCE Security |
Md5 | Version 3: Md5 hash |
Random | Version 4: Random |
Sha1 | Version 5: Sha1 hash |
Benchmarks
Lower is better.
benchmark | uuid-rs (ns) | yauuid (ns) |
---|---|---|
parse_str | 70.240 | 33.176 |
to_string | 107.48 | 75.387 |
new_v1 | 6.1016 | 6.1530 |
new_v3 | 211.16 | 174.33 |
new_v4 | 29.946 | 30.557 |
new_v5 | 209.24 | 212.94 |
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.
