Struct Sha256

pub struct Sha256 { /* private fields */ }

SHA-256 hash function state with enhanced memory safety

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 Drop for Sha256

fn drop(&mut self)

Executes the destructor for this type.

impl HashFunction for Sha256

type Algorithm = Sha256Algorithm

The algorithm type that defines constants and properties

type Output = Digest<SHA256_OUTPUT_SIZE>

The output digest type with size guarantees

fn new() -> Self

Creates a new instance of the hash function.

fn update(&mut self, data: &[u8]) -> Result<&mut Self>

Updates the hash state with data, returning self for chaining.

fn finalize(&mut self) -> Result<Self::Output>

Finalizes and returns the digest.

fn output_size() -> usize

The output size in bytes.

fn block_size() -> usize

The internal block size in bytes.

fn name() -> String

Human-readable name.

fn finalize_reset(&mut self) -> Result<Self::Output>

Finalizes, returns the digest, and resets state.

fn digest(data: &[u8]) -> Result<Self::Output>

Convenience: one-shot digest computation with fluent interface.

fn verify(data: &[u8], expected: &Self::Output) -> Result<bool>

where Self::Output: PartialEq,

Convenience method to verify a hash against input data

impl SecureZeroingType for Sha256

fn zeroed() -> Self

Create a zeroed instance

fn secure_clone(&self) -> Self

Create a secure clone that preserves security properties

impl Zeroize for Sha256

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
