The possible multihash variants.

Variants

Identity

A straight copy of the data supposedly hashed. May be a prefix rather than a full copy.

Sha1

A 160-bit SHA-1 digest.

Sha2_256

A 256-bit SHA-2 digest.

Sha2_512

A 512-bit SHA-2 digest.

Sha3_512

A 512-bit SHA-3 digest.

Sha3_384

A 384-bit SHA-3 digest.

Sha3_256

A 256-bit SHA-3 digest.

Sha3_224

A 224-bit SHA-3 digest.

Shake128

A variable size SHAKE-128 digest.

Shake256

A variable size SHAKE-256 digest.

Blake2B

A 512-bit BLAKE2b digest.

Blake2S

A 256-bit BLAKE2s digest.

ApplicationSpecific

An application specific MultiHash variant.

Fields of ApplicationSpecific

code: usize

The application specific code for this variant, must be in the range [0x0400, 0x040f].

Methods

impl MultiHashVariant

fn from_code(code: usize) -> Result<MultiHashVariant>

Returns the multihash variant that the given code refers to, validates that the code is known or an application specific variant.

fn from_code_and_length(code: usize, length: usize) -> Result<MultiHashVariant>

Returns the multihash variant that the given code refers to, 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 check_length(self, length: usize) -> Result<()>

Validates that the length is consistent with this multihash variant.

fn max_len(self) -> usize

The maximum digest length allowed for this multihash variant.

fn code(self) -> usize

The code specifying this multihash variant.

fn name(self) -> &'static str

The string representation of this multihash type.
