xid
Globally unique sortable id generator. A Rust port of https://github.com/rs/xid.
The binary representation is compatible with the Mongo DB 12-byte ObjectId. The value consists of:
- a 4-byte timestamp value in seconds since the Unix epoch
- a 3-byte value based on the machine identifier
- a 2-byte value based on the process id
- a 3-byte incrementing counter, initialized to a random value
The string representation is 20 bytes, using a base32 hex variant with characters [0-9a-v]
to retain the sortable property of the id.
See the original xid project for more details.
Usage
println!("{}", xid::new()); //=> bva9lbqn1bt68k8mj62g
Examples
cargo run --example gen: Generate xid
