Struct nettle::hash::Sha224

pub struct Sha224 { /* fields omitted */ }

256 bit variant of the Secure Hash Algorithm 2 (SHA-2) defined in FIPS 180-4, truncated to 224 bit.

Trait Implementations

impl Clone for Sha224

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Sha224

fn default() -> Self

Returns the "default value" for a type.

impl Hash for Sha224

fn digest_size(&self) -> usize

Size of the digest in bytes

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

Writes data into the hash function.

fn digest(&mut self, digest: &mut [u8])

Finalizes the hash function and writes the digest into the provided slice. digest must be at least DIGEST_SIZE bytes large, otherwise the digest will be truncated. Resets the hash function contexts.

fn box_clone(&self) -> Box<dyn Hash>

Clones the hash context into a Box.

impl NettleHash for Sha224

type Context = sha256_ctx

unsafe fn nettle_hash() -> &'static nettle_hash

Pointer to the nettle_hash structure for this hash.

impl Pkcs1Hash for Sha224

fn oid(&self) -> &'static [u8]

Internal to sign_pkcs1 and verify_pkcs1.

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.

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

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

pub 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.

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

Attempts to write an entire buffer into this writer.

pub 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.

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

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

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

Creates a "by reference" adaptor for this instance of Write.
