Expand description

Trait that implements hashing.

It is usually implemented by a custom code table enum that derives the Multihash derive.

Required Methods§

Source

fn digest(&self, input: &[u8]) -> Multihash<S>

Calculate the hash of some input data.

§Example
// `Code` implements `MultihashDigest`
use multihash::{Code, MultihashDigest};

let hash = Code::Sha3_256.digest(b"Hello world!");
println!("{:02x?}", hash);
Source

fn wrap(&self, digest: &[u8]) -> Result<Multihash<S>, Error>

Create a multihash from an existing multihash digest.

§Example
use multihash::{Code, Hasher, MultihashDigest, Sha3_256};

let mut hasher = Sha3_256::default();
hasher.update(b"Hello world!");
let hash = Code::Sha3_256.wrap(&hasher.finalize()).unwrap();
println!("{:02x?}", hash);

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
