Trait Implementations§

source§

impl Clone for Impl

source§

fn clone(&self) -> Impl

Returns a copy of the value. Read more
1.0.0 · source§

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

Performs copy-assignment from source. Read more
source§

impl Debug for Impl

source§

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

Formats the value using the given formatter. Read more
source§

impl Default for Impl

source§

fn default() -> Impl

Returns the “default value” for a type. Read more
source§

impl Sha256 for Impl

§

type DigestPtr = &'static mut Digest

A pointer to the digest created as the result of a hashing operation. Read more
source§

fn hash_bytes(bytes: &[u8]) -> Self::DigestPtr

Generate a SHA-256 hash from a slice of bytes, padding to block size and adding the SHA-256 hash trailer, as specified in FIPS 180-4.
source§

fn hash_words(words: &[u32]) -> Self::DigestPtr

Generate a SHA-256 hash from a slice of words, padding to block size and adding the SHA-256 hash trailer, as specified in FIPS 180-4.
source§

fn hash_raw_pod_slice<T: Pod>(pod: &[T]) -> Self::DigestPtr

Generate a hash from a slice of anything that can be represented as plain old data. Pads up to the SHA-256 block boundary, but does not add the standard SHA-256 trailer and so is not a standards compliant hash.
source§

fn compress( state: &Digest, block_half1: &Digest, block_half2: &Digest ) -> Self::DigestPtr

Execute the SHA-256 compression function on a single block given as two half-blocks and return a pointer to the result. Read more
source§

fn compress_slice(state: &Digest, blocks: &[Block]) -> Self::DigestPtr

Execute the SHA-256 compression function on a slice of blocks following the Merkle–Damgård construction and return a pointer to the result. Read more
source§

fn hash_pair(a: &Digest, b: &Digest) -> Self::DigestPtr

Generate a hash from a pair of Digest using the SHA-256 compression function. Note that the result is not a standard-compliant hash of any kwown preimage.
