[]Struct sc_network::multiaddr::multihash::MultihashGeneric

pub struct MultihashGeneric<S> where
    S: Size
{ /* fields omitted */ }

A Multihash instance that only supports the basic functionality and no hashing.

With this Multihash implementation you can operate on Multihashes in a generic way, but no hasher implementation is associated with the code.

Example

use multihash::Multihash;

const Sha3_256: u64 = 0x16;
let digest_bytes = [
    0x16, 0x20, 0x64, 0x4b, 0xcc, 0x7e, 0x56, 0x43, 0x73, 0x04, 0x09, 0x99, 0xaa, 0xc8, 0x9e,
    0x76, 0x22, 0xf3, 0xca, 0x71, 0xfb, 0xa1, 0xd9, 0x72, 0xfd, 0x94, 0xa3, 0x1c, 0x3b, 0xfb,
    0xf2, 0x4e, 0x39, 0x38,
];
let mh = Multihash::from_bytes(&digest_bytes).unwrap();
assert_eq!(mh.code(), Sha3_256);
assert_eq!(mh.size(), 32);
assert_eq!(mh.digest(), &digest_bytes[2..]);

Implementations

impl<S> Multihash<S> where
    S: Size

pub fn wrap(code: u64, input_digest: &[u8]) -> Result<Multihash<S>, Error>

Wraps the digest in a multihash.

pub fn code(&self) -> u64

Returns the code of the multihash.

pub fn size(&self) -> u8

Returns the size of the digest.

pub fn digest(&self) -> &[u8]

Returns the digest.

pub fn read<R>(r: R) -> Result<Multihash<S>, Error> where
    R: Read,
    Multihash<S>: Sized

Reads a multihash from a byte stream.

pub fn from_bytes(bytes: &[u8]) -> Result<Multihash<S>, Error> where
    Multihash<S>: Sized

Parses a multihash from a bytes.

You need to make sure the passed in bytes have the correct length. The digest length needs to match the size value of the multihash.

pub fn write<W>(&self, w: W) -> Result<(), Error> where
    W: Write

Writes a multihash to a byte stream.

pub fn to_bytes(&self) -> Vec<u8, Global>

Returns the bytes of a multihash.
