lid (Lily's ID)

I wanted something that I could trust with being unique enough, while also being extremely fast and light on system resources.

For some of my projects I used a flakeid implementation I wrote in Rust, but this requires it to be ran as its own service per-machine if it's being shared by multiple services.

By default this uses Base32 and 28 bytes total, This gives approx. 1393796574908163946345982392040522594123776 (32^28) possible IDs.

Example usage

use lid::LID;

fn main() {
    // This uses the global Mutex LID instance. It's slightly slower due to the Mutex.
    println!("{}", lid::generate_lid());

    let mut lid = LID::default();
    println!("{}", lid.generate());
}
