Struct Sha256 

pub struct Sha256 { /* private fields */ }

Implements SHA-256 compression and streaming digest state.

Implementations

impl Sha256

pub fn new() -> Self

Creates a new SHA-256 hasher initialized with standard IV constants.

Returns

A fresh Sha256 instance with empty input state.

Panics

This function does not panic.

Trait Implementations

impl Clone for Sha256

fn clone(&self) -> Sha256

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sha256

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

Formats the value using the given formatter.

impl Default for Sha256

fn default() -> Self

Builds a SHA-256 hasher with standard IV constants and an empty buffer.

Returns

Fresh Sha256 in the initial state.

Panics

This function does not panic.

impl Digest for Sha256

fn update(&mut self, data: &[u8])

Absorbs data into the running digest, compressing whenever 64 bytes accumulate.

Arguments

• self — Running SHA-256 hasher.
• data — Next message bytes to append.

Returns

().

Panics

This function does not panic.

fn finalize(self) -> Vec<u8>

Finalizes SHA-256 padding and returns the 32-byte digest in a newly allocated vector.

Arguments

• self — Consumed hasher holding buffered tail bytes and the bit length.

Returns

Vec containing exactly 32 digest bytes (big-endian words from internal state).

Panics

This function does not panic.
