Struct Tag 

pub struct Tag { /* private fields */ }

Represents the authentication tag for AEADs

Implementations

impl Tag

pub const CAPACITY: usize = 16usize

The size of the authentication tag in bytes.

pub const fn new(inner: [u8; 16]) -> Self

Creates a new Tag instance from a 16-byte array.

Arguments

• inner - A 16-byte array containing the authentication tag.

Returns

A new Tag instance.

pub const fn new_zeroed() -> Self

Creates a new Tag instance filled with zeros.

This is typically used to create a tag buffer that will be filled by an encryption operation.

Returns

A new Tag instance with all bytes set to zero.

Example

use wolf_crypto::aead::Tag;

let tag = Tag::new_zeroed();
assert_eq!(tag.as_slice(), &[0u8; 16]);

pub const fn take(self) -> [u8; 16]

Consumes the Tag and returns the underlying 16-byte array.

pub const fn as_slice(&self) -> &[u8]

Returns a reference to the tag as a byte slice.

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl<T> PartialEq<&T> for Tag

where Self: PartialEq<T>, T: ?Sized,

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

PartialEq for references of types which already can be compared to Tag in constant time.

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<T> PartialEq<&mut T> for Tag

where Self: PartialEq<T>, T: ?Sized,

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

PartialEq for references of types which already can be compared to Tag in constant time.

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 PartialEq<[u8]> for Tag

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

Constant Time Equivalence (variable timing for length of other)

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