Struct Algorithm

pub struct Algorithm { /* private fields */ }

A digest algorithm.

Implementations

impl Algorithm

pub fn block_len(&self) -> usize

The internal block length.

pub fn chaining_len(&self) -> usize

The size of the chaining value of the digest function, in bytes.

For non-truncated algorithms (SHA-1, SHA-256, SHA-512), this is equal to Self::output_len(). For truncated algorithms (e.g. SHA-384, SHA-512/256), this is equal to the length before truncation. This is mostly helpful for determining the size of an HMAC key that is appropriate for the digest algorithm.

pub fn output_len(&self) -> usize

The length of a finalized digest.

Trait Implementations

impl Debug for Algorithm

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

Formats the value using the given formatter.

impl PartialEq for Algorithm

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
