//! An implementation of the [GOST R 34.11-94][1] cryptographic hash algorithm.
//!
//! # Usage
//! ```rust
//! use gost94::{Gost94CryptoPro, Digest};
//! use hex_literal::hex;
//!
//! // create Gost94 hasher instance with CryptoPro params
//! let mut hasher = Gost94CryptoPro::new();
//!
//! // process input message
//! hasher.update("The quick brown fox jumps over the lazy dog");
//!
//! // acquire hash digest in the form of GenericArray,
//! // which in this case is equivalent to [u8; 32]
//! let result = hasher.finalize();
//! assert_eq!(result[..], hex!("
//!     9004294a361a508c586fe53d1f1b02746765e71b765472786e4770d565830a76
//! "));
//! ```
