Struct HashEngine

pub struct HashEngine { /* private fields */ }

Engine to compute SHA512 hash function.

Trait Implementations

impl Clone for HashEngine

fn clone(&self) -> HashEngine

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for HashEngine

fn default() -> HashEngine

Returns the “default value” for a type.

impl HashEngine for HashEngine

const BLOCK_SIZE: usize = 128usize

Length of the hash’s internal block size, in bytes.

type MidState = [u8; 64]

Byte array representing the internal state of the hash engine.

fn midstate(&self) -> [u8; 64]

Outputs the midstate of the hash engine. This function should not be used directly unless you really know what you’re doing.

fn n_bytes_hashed(&self) -> usize

Return the number of bytes already n_bytes_hashed(inputted).

fn input(&mut self, inp: &[u8])

Add data to the hash engine.

impl Write for HashEngine

fn flush(&mut self) -> Result<(), Error>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write(&mut self, buf: &[u8]) -> Result<usize, Error>

Writes a buffer into this writer, returning how many bytes were written.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
