Struct multihash::MultihashRefGeneric

pub struct MultihashRefGeneric<'a, T> { /* fields omitted */ }

Represents a valid multihash.

Implementations

impl<'a, T: TryFrom<u64>> MultihashRefGeneric<'a, T>

pub fn from_slice(input: &'a [u8]) -> Result<Self, DecodeError>

Creates a new MultihashRef from a &[u8]. If the input data is not a valid multihash an error is returned.

Example

use multihash::{MultihashRef, Sha2_256};

let mh = Sha2_256::digest(b"hello world");

// valid multihash
let mh2 = MultihashRef::from_slice(&mh).unwrap();

// invalid multihash
assert!(MultihashRef::from_slice(&vec![1, 2, 3]).is_err());

pub fn algorithm(&self) -> T

Returns the algorithm used in this multihash.

Example

use multihash::{Code, MultihashRef, Sha2_256};

let mh = Sha2_256::digest(b"hello world");

// valid multihash
let mh2 = MultihashRef::from_slice(&mh).unwrap();
assert_eq!(mh2.algorithm(), Code::Sha2_256);

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

Returns the hash digest.

Example

use multihash::{wrap, Code, Multihash, Sha2_256};

let mh = Sha2_256::digest(b"hello world");
let digest = mh.digest();
let wrapped: Multihash = wrap(Code::Sha2_256, &digest);
assert_eq!(wrapped.digest(), digest);

pub fn to_owned(&self) -> MultihashGeneric<T>

Builds a Multihash that owns the data.

This operation allocates.

pub fn as_bytes(&self) -> &'a [u8]

Returns the bytes representation of this multihash.
