Struct Digest 

pub struct Digest { /* private fields */ }

Digest represents the partial evaluation of a checksum. The low 16 bits are s1, the high 16 bits are s2.

Implementations

impl Digest

pub fn new() -> Self

Trait Implementations

impl Default for Digest

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Digest

fn reset(&mut self)

reset resets the Hash to its initial state.

fn size(&self) -> usize

size returns the number of bytes Sum will return.

fn block_size(&self) -> usize

block_size returns the hash’s underlying block size. The Write method must be able to accept any amount of data, but it may operate more efficiently if all writes are a multiple of the block size.

fn sum(&self, b: &[u8]) -> Vec<u8>

sum appends the current hash to b and returns the resulting slice. It does not change the underlying hash state.

impl Hash32 for Digest

fn sum32(&self) -> u32

impl Write for Digest

fn write(&mut self, buf: &[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.
