Struct Sha256Compression 

pub struct Sha256Compression { /* private fields */ }

A two-to-one compression function for SHA-256 digests.

One raw block compression of left || right, from a domain-separated initial state. This is not a full hash of the pair: there is no padding block and no length suffix.

Implementations

impl Sha256Compression

pub const fn initial_state(&self) -> &[u32; 8]

The domain-separated state every compression starts from.

A batched implementation has to seed its lanes with exactly these words to agree with this one, so the state is part of the public contract rather than an internal detail.

Trait Implementations

impl Clone for Sha256Compression

fn clone(&self) -> Sha256Compression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CompressionFunction<Array<u8, <Sha256 as OutputSizeUser>::OutputSize>, 2> for Sha256Compression

fn compress(&self, input: [Output<Sha256>; 2]) -> Output<Sha256>

Maps the N inputs down to a single output of the same type.

impl Debug for Sha256Compression

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

Formats the value using the given formatter.

impl Default for Sha256Compression

fn default() -> Self

Returns the “default value” for a type.
