Crate snowflake_me
source ·Expand description
A distributed unique ID generator inspired by Twitter’s Snowflake.
This is a Rust implementation of the original [houseme/snowflake-rs], which is written in Go.
Quickstart
Add the following to your Cargo.toml
:
[dependencies]
snowflake_me = "0.1"
Use the library like this:
use snowflake_me::Snowflake;
let sf = Snowflake::new().unwrap();
let next_id = sf.next_id().unwrap();
println!("{}", next_id);
Concurrent use
Snowflake is threadSafe. clone
it before moving to another thread:
use snowflake_me::Snowflake;
use std::thread;
let sf = Snowflake::new().unwrap();
let mut children = Vec::new();
for _ in 0..10 {
let mut thread_sf = sf.clone();
children.push(thread::spawn(move || {
println!("{}", thread_sf.next_id().unwrap());
}));
}
for child in children {
child.join().unwrap();
}
