rs-nanoid
This crate is the most efficient implementation of ai/nanoid.
Features of the Nano ID spec are:
- URL friendly
- Use of cryptographic random generator
- Uses a bigger alphabet than UUID, so a similar number of random bits are packed in just 21 chars instead of 36 (like UUID)
- Much, much faster than UUID (v4)
Features of this specific implementation are:
- Fastest and most performant implementation of Nano ID around (benchmarks)
- Minimal memory usage.
- Fully optimized (
nanoid::standardandnanoid::standard_unsecure).

Install
Add to Cargo.toml under [dependencies].
rs-nanoid = "0.1.0"
Security
If 1,000,000 Nano IDs of length 21 (a.k.a.
nanoid::standard::<21>) were generated each second, ~41 thousand years would be required in order to have a 1.0% probability of a collision.
Comparison of Nano ID and UUID (V4).
Benchmarks
Tests are inside of lib.rs and benchmarks are in the benches folder.
These are benchmarks of nanoid::standard::<length>().
