Struct Algorithm

pub struct Algorithm {
    pub output_len: usize,
    pub chaining_len: usize,
    pub block_len: usize,
    /* private fields */
}

A digest algorithm.

Fields

output_len: usize

The length of a finalized digest.

chaining_len: usize

👎Deprecated

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 output_len. For truncated algorithms (e.g. SHA-224, 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.

This function isn’t actually used in aws-lc-rs, and is only kept for compatibility with the original ring implementation.

block_len: usize

The internal block length.

Implementations

impl Algorithm

pub fn output_len(&self) -> usize

The length of a finalized digest.

pub fn chaining_len(&self) -> usize

pub fn block_len(&self) -> usize

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: &Algorithm) -> 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
