Struct commoncrypto::hash::Hasher

pub struct Hasher { /* fields omitted */ }

Generates cryptographic hashes.

Methods

impl Hasher

fn new(algorithm: CCDigestAlgorithm) -> Hasher

Creates a new Hasher which will use the given cryptographic algorithm.

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

Feeds data into the hasher.

fn finish(&mut self) -> Result<Vec<u8>>

Finalizes digest operations and produces the digest output.

Trait Implementations

impl Debug for Hasher

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Write for Hasher

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

Write a buffer into this object, 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_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this write.

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" adaptor for this instance of Write.

impl Drop for Hasher

fn drop(&mut self)

A method called when the value goes out of scope.
