Struct sha2::Sha224

pub struct Sha224 { /* fields omitted */ }

The SHA-256 hash algorithm with the SHA-224 initial hash value. The result is truncated to 224 bits.

Trait Implementations

impl BlockInput for Sha224

type BlockSize = U64

Block size

impl Clone for Sha224

fn clone(&self) -> Sha224

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sha224

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

Formats the value using the given formatter.

impl Default for Sha224

fn default() -> Self

Returns the “default value” for a type.

impl FixedOutputDirty for Sha224

type OutputSize = U28

Output size for fixed output digest

fn finalize_into_dirty(&mut self, out: &mut Output<Self>)

Retrieve result into provided buffer and leave hasher in a dirty state.

impl Reset for Sha224

fn reset(&mut self)

Reset hasher instance to its initial state and return current state.

impl Update for Sha224

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

Digest input data.

fn chain(self, data: impl AsRef<[u8]>) -> Self

Digest input data in a chained manner.

impl Write for Sha224

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

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

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

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

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

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