A distributed unique ID generator inspired by Twitter's Snowflake.
This is a Rust implementation of the original sony/sonyflake, which is written in Go.
A Sonyflake ID is composed of
- 39 bits for time in units of 10 msec
- 8 bits for a sequence number
- 16 bits for a machine id
Add the following to your Cargo.toml:
[dependencies]
sonyflake = "0.2"use sonyflake::Sonyflake;
let sf = Sonyflake::new().unwrap();
let next_id = sf.next_id().unwrap();
println!("{}", next_id);Benchmarks were run on a MacBook Pro (15-inch, 2017) with a 2,8GHz i7 and 16 GB memory.
Run them yourself with cargo bench.
