//! Cryptographic Hash Functions root module
//!
//! The simplest way to use this module is to use the function, named
//! after each algorithm, that calculate the digest in one single call:
//!
//! ```
//! use cryptoxide::hashing::sha256;
//!
//! let digest = sha256(b"The quick brown fox jumps over the lazy dog");
//! ```
//!
//! Each individual algorithm is also available as a module that should
//! be imported qualified and export algorithm singleton for each variant
//! of this algorithm along with a `Context` object.
//!
//! The `Context` object keeps the ongoing state of the algorithm, so
//! that the input can be hashed incrementally with either `update` or
//! `update_mut`. Once all the data has been hashed the `Context`
//! can be finalized using `finalize` or `finalize_reset`.
//!
//! The APIs can be used either in a pass-the-context api:
//!
//! ```
//! use cryptoxide::hashing::sha2;
//!
//! let digest = sha2::Context256::new()
//!         .update(b"The quick brown fox jumps over the lazy dog")
//!         .update(b"other data")
//!         .finalize();
//! ```
//!
//! Or using the inplace mutable APIs:
//!
//! ```
//! use cryptoxide::hashing::sha2;
//!
//! let mut context = sha2::Context256::new();
//! context.update_mut(b"The quick brown fox jumps over the lazy dog");
//! context.update_mut(b"other data");
//! let digest = context.finalize_reset();
//! ```
//!
