# pairing [](https://crates.io/crates/pairing) #
This is a Rust crate for using pairing-friendly elliptic curves. Currently, only the [BLS12-381](https://z.cash/blog/new-snark-curve.html) construction is implemented.
## [Documentation](https://docs.rs/pairing/)
Bring the `pairing` crate into your project just as you normally would.
If you're using a supported platform and the nightly Rust compiler, you can enable the `u128-support` feature for faster arithmetic.
```toml
[dependencies.pairing]
version = "0.13"
features = ["u128-support"]
```
