YYID generator in Rust

GitHub Workflow Status (branch) yyid on crates.io yyid documentation

Generates random tokens that look like type 4 UUIDs: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

In contrast to RFC 4122, it uses all digits (128bit).

Source of randomness: getrandom

Examples

Rust

Add yyid = "*" to your dependencies section in Cargo.toml.

use yyid::*;

fn main() {
    println!("{}", Yyid::new());
    // => "02e7f0f6-067e-8c92-b25c-12c9180540a9"
}

Notes

  • The current implementation is derived from the uuid crate
  • It does not implement everything (no parsing, only generation of tokens)
  • Functionality will also be reduced down to the reference implementations (see Also Available As)
  • The default format is with hyphens (more human readable by default, only 4 bytes extra)
  • For simplicity only the *Ref types are implemented (no owning structures); format at the latest point possible
