//! Multihash implementation.
//!
//! Feature Flags
//! -------------
//!
//! Multihash has lots of [feature flags], by default a table with cryptographically secure hashers
//! is created.
//!
//! Some of the features are about specific hash functions, these are ("default" marks the hashers
//! that are enabled by default):
//!
//! - `blake2b`: (default) Enable Blake2b hashers
//! - `blake2s`: (default) Enable Blake2s hashers
//! - `identity`: Enable the Identity hashers (using it is discouraged as it's not a hash function
//! in the sense that it produces a fixed sized output independent of the input size)
//! - `sha1`: Enable SHA-1 hasher
//! - `sha2`: (default) Enable SHA-2 hashers
//! - `sha3`: (default) Enable SHA-3 hashers
//! - `strobe`: Enable Strobe hashers
//!
//! In order to enable all cryptographically secure hashers, you can set the `secure-hashes`
//! feature flag (enabled by default).
//!
//! The library has support for `no_std`, if you disable the `std` feature flag.
//!
//! The `multihash-impl` feature flag (enabled by default) enables a default Multihash
//! implementation that contains some of the bundled hashers. If you want a different set of hash
//! algorithms you can change this with enabled the corresponding features.
//!
//! For example if you only need SHA2 hasher, you could set the features in the `multihash`
//! dependency like this:
//!
//! ```toml
//! multihash = { version = …, default-features = false, features = ["std", "multihash-impl", "sha2"] }
//! ```
//!
//! If you want to customize your code table even more, for example you want only one specific hash
//! digest size and not whole family, you would only enable the `derive` feature (enabled by
//! default), which enables the [`Multihash` derive], together with the hashers you want.
//!
//! The `arb` feature flag enables the quickcheck arbitrary implementation for property based
//! testing.
//!
//! For serializing the multihash there is support for [Serde] via the `serde-codec` feature and
//! the [SCALE Codec] via the `scale-codec` feature.
//!
//! [feature flags]: https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section
//! [`Multihash` derive]: crate::derive
//! [Serde]: https://serde.rs
//! [SCALE Codec]: https://github.com/paritytech/parity-scale-codec
