Struct SHA2_256_x86 

pub struct SHA2_256_x86 { /* private fields */ }

An x86 and x86_64 optimized implementation of the SHA2_256 algorithm.

This implementation is only available on x86 and x86_64 targets. The code will panic if the target is invalid.

Safety

This implementation does not verify that the target supports the required instructions. In particular sha,sse4.1 features have to be supported. Otherwise the code will likely crash at runtime.

Implementations

impl SHA2_256_x86

pub const fn new() -> Self

Creates a new SHA2_256_x86 instance.

Panics

If target_arch is neither x86 nor x86_64.

pub fn update(&mut self, data: impl AsRef<[u8]>)

Writes a block of data to the underlying state.

pub fn result(&self, output: &mut [u8; 32])

Calculates the final hash value.

Trait Implementations

impl Default for SHA2_256_x86

fn default() -> Self

Returns the “default value” for a type.

impl From<SHA2_256_Portable> for SHA2_256_x86

fn from(portable: SHA2_256_Portable) -> Self

Converts to this type from the input type.

impl From<SHA2_256_x86> for SHA2_256_Portable

fn from(x86: SHA2_256_x86) -> Self

Converts to this type from the input type.

impl HashFunction for SHA2_256_x86

type Output = [u8; 32]

fn update(&mut self, data: impl AsRef<[u8]>)

Updates the internal state of the HashFunction with given data.

fn write_result(&self, output: &mut Self::Output)

Writes the final result to the output passed as ref parameter.

fn result(&self) -> Self::Output

A wrapper around HashFunction::write_result that returns the hash instead of writing it to output parameter.
