Multihash

Multiformats Multihash implementation without constant size in the type signature.

Features

• Uses the [multiutil::BaseEncoded] smart pointers to wrap the Multihash into EncodecMultihash for base encoded multihashes; automating the encoding/decoding to/from strings and byte slices.
• Serde support to/from human readable and binary formats.
• Supports raw binary encoding and decoding using [Into<Vec<u8>>] and [TryFrom<&[u8]>] trait implementations.

Examples

Bulding a multihash from some bytes:

let mh = Builder::new_from_bytes(Codec::Sha3384, b"for great justice, move every zig!")?
    .try_build()?;

Building a base encoded multihash from some bytes:

let encoded_mh = Builder::new_from_bytes(Codec::Sha3256, b"for great justice, move every zig!")?
    .with_base_encoding(Base::Base58Btc)
    .try_build_encoded()?;

Existing multihash objects can be converted to [crate::mh::EncodedMultihash] objects by using .into():

let mh = Builder::new_from_bytes(Codec::Sha3384, b"for great justice, move every zig!")?
    .try_build()?;

// this will use the preferred encoding for multihash objects: Base::Base16Lower
let encoded_mh1: EncodedMultihash = mh.into();

// or you can chose the base enccoding...
let encoded_mh2: EncodedMultihash::new(Base::Base32Upper, mh);
