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.

impl Eq for Algorithm

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
