Struct mhash::MultiHash

pub struct MultiHash { /* fields omitted */ }

A decoded multihash.

Methods

impl MultiHash

fn new(variant: MultiHashVariant, digest: &[u8]) -> Result<MultiHash>

Create a new multihash with the specified variant and digest. Validates the length of the digest is consistent with the multihash variant.

fn new_with_code(code: usize, digest: &[u8]) -> Result<MultiHash>

Create a new multihash with the specified code and digest, validates that the code is known or an application specific variant, and that the length is consistent with the multihash variant the code refers to.

fn len(&self) -> usize

The length of this multihash's digest.

fn variant(&self) -> MultiHashVariant

This multihash's variant.

fn code(&self) -> usize

The code specifying this multihash variant.

fn name(&self) -> &'static str

The string representation of this multihash type.

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

A reference to the bytes making up the digest of this multihash.

impl MultiHash

fn from_bytes(bytes: &[u8]) -> Result<MultiHash>

Parse a binary encoded multihash

impl MultiHash

fn to_bytes(&self) -> Vec<u8>

Create a Vec<u8> with the binary encoding of this multihash.

fn output_len(&self) -> usize

The length this multihash will use when serialized to a byte array/stream.

Trait Implementations

impl Eq for MultiHash

fn clone(&self) -> MultiHash

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Hash for MultiHash

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Debug for MultiHash

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for MultiHash

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl FromStr for MultiHash

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<MultiHash>

Parses a string s to return a value of this type.
