//! Hashing functions.
//!
//! This module is gated by `full-crypto` feature. If you intend to use any of the functions
//! defined here within your runtime, you should most likely rather use `sp_io::hashing` instead,
//! unless you know what you're doing. Using `sp_io` will be more performant, since instead of
//! computing the hash in WASM it delegates that computation to the host client.
