pub struct Sha256(/* private fields */);

SHA-256 hash algorithm

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 Debug for Sha256

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

Formats the value using the given formatter.

impl Default for Sha256

fn default() -> Sha256

Returns the “default value” for a type.

impl Hash for Sha256

fn new() -> Self

Constructs a new hash.

fn block_size() -> usize

Returns the block size of the hash, in bytes.

fn reset(&mut self)

Resets the hash.

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

Updates the hash with some data.

fn finalize<'a>(&'a mut self) -> &'a [u8]

Finalizes the hash and return the digest.

fn new_with_prefix(data: &[u8]) -> Self

where Self: Sized,

Constructs a new hash and updates it with some data.

impl Write for Sha256

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

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

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

Flushes 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, args: 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.
