Struct Sha256 

pub struct Sha256 { /* private fields */ }

Streaming SHA-256 state.

Buffers up to 64 bytes (one compression-function block) before processing. len_bits tracks the total message length so the padding step can write the canonical 64-bit big-endian length suffix even when the caller supplies bytes in many small chunks.

Implementations

impl Sha256

pub const fn new() -> Self

Construct a fresh hasher with the standard initial state.

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

Absorb data into the running hash. Safe to call repeatedly with arbitrary chunk sizes — partial blocks are buffered.

pub fn finalize(self) -> [u8; 32]

Finalize the hash, returning the 32-byte digest. Consumes self.
