Struct Digest 

pub struct Digest<D: Digest> { /* private fields */ }

Utility wrapper around the final HMAC hash.

Implementations

impl<D: Digest + Copy> Digest<D>

pub const fn new(digest: D) -> Self

Create a new Digest instance.

pub const fn into_inner(self) -> D

Unwraps this Digest returning the raw byte array.

Note

Comparing Digests should always be in constant-time, do not use into_inner prior to checking equivalence between Digests. The Digest type’s PartialEq implementations are all in constant-time. Either leverage these, or use this crate’s ct_eq function.

pub fn hex_encode(&self) -> HexDigest<D::Hex>

Hex-encodes the underlying digest in constant-time, returning the HexDigest type.

Trait Implementations

impl<D: Digest> AsRef<[u8]> for Digest<D>

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

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

impl<D: Digest> AsRef<D> for Digest<D>

fn as_ref(&self) -> &D

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

impl<D: Clone + Digest> Clone for Digest<D>

fn clone(&self) -> Digest<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<D: Digest> Debug for Digest<D>

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

Writes “Digest { … }” to the provided formatter.

impl<D: Digest> From<Digest<D>> for HexDigest<D::Hex>

fn from(value: Digest<D>) -> Self

Converts to this type from the input type.

impl<D: HexDigest> From<HexDigest<D>> for Digest<D::Digest>

fn from(value: HexDigest<D>) -> Self

Converts to this type from the input type.

impl<D: Digest, T> PartialEq<&T> for Digest<D>

where Self: PartialEq<T>,

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

Constant-Time Equivalence.

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<D: Digest, T> PartialEq<&mut T> for Digest<D>

where Self: PartialEq<T>,

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

Constant-Time Equivalence.

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<D: Digest> PartialEq<[u8]> for Digest<D>

fn eq(&self, other: &[u8]) -> bool

Constant-Time Equivalence.

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<D: Digest> PartialEq for Digest<D>

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

Constant-Time Equivalence.

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

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