Struct HmacTag 

pub struct HmacTag { /* private fields */ }

HMAC authentication tag bytes.

Implementations

impl HmacTag

pub fn from_slice( algorithm: MacAlgorithm, input: &[u8], ) -> Result<HmacTag, CryptoError>

Constructs a tag from fixed-size bytes for algorithm.

pub fn as_bytes(&self) -> &[u8]

Borrows the tag bytes.

pub fn len(&self) -> usize

Returns the tag length in bytes.

pub fn is_empty(&self) -> bool

Returns whether this tag contains zero bytes.

pub fn into_vec(self) -> Vec<u8>

Consumes the tag and returns the owned tag bytes.

Trait Implementations

impl Clone for HmacTag

fn clone(&self) -> HmacTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HmacTag

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

Formats the value using the given formatter.

impl Drop for HmacTag

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Eq for HmacTag

impl PartialEq for HmacTag

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

Equality operator ==.

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

Inequality operator !=.

impl Zeroize for HmacTag

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
