Struct Digest 

pub struct Digest { /* private fields */ }

A calculated digest value.

Use Self::as_ref to get the value as a &[u8].

Implementations

impl Digest

pub fn import_less_safe( digest: &[u8], algorithm: &'static Algorithm, ) -> Result<Self, Unspecified>

Imports a digest value provide by an external source. This allows for the signing of content that might not be directly accessible.

WARNING: Ensure that the digest is provided by a trusted source. When possible, prefer to directly compute the digest of content.

Errors

Returns Unspecified if the imported value is the wrong length for the specified algorithm.

pub fn algorithm(&self) -> &'static Algorithm

The algorithm that was used to calculate the digest value.

Trait Implementations

impl AsRef<[u8]> for Digest

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Digest

fn clone(&self) -> Digest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Digest

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

Formats the value using the given formatter.

impl Copy for Digest
