Expand description

The Digest trait specifies an interface common to digest functions, such as SHA-1 and the SHA-2 family of digest functions.

Required Methods§

Source

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

Provide message data.

§Arguments
  • input - A vector of message data
Source

fn result(&mut self, out: &mut [u8])

Retrieve the digest result. This method may be called multiple times.

§Arguments
  • out - the vector to hold the result. Must be large enough to contain output_bits().
Source

fn reset(&mut self)

Reset the digest. This method must be called after result() and before supplying more data.

Source

fn output_bits(&self) -> usize

Get the output size in bits.

Source

fn block_size(&self) -> usize

Get the block size in bytes.

Provided Methods§

Source

fn output_bytes(&self) -> usize

Get the output size in bytes.

Source

fn input_str(&mut self, input: &str)

Convenience function that feeds a string into a digest.

§Arguments
  • input The string to feed into the digest
Source

fn result_str(&mut self) -> String

Convenience function that retrieves the result of a digest as a String in hexadecimal format.
