Struct ThreefishParamsRef 

pub struct ThreefishParamsRef<'a> { /* private fields */ }

A borrowed key with an optional borrowed tweak.

This type does not validate either value; the selected Threefish engine performs validation when it is initialized. Callers with their own parameter type can implement KeyParams and ThreefishParams directly. Constant time: construction and access do not inspect key or tweak contents.

Implementations

impl<'a> ThreefishParamsRef<'a>

pub const fn new(key: &'a [u8]) -> Self

Uses key with Threefish’s all-zero tweak. Constant time.

pub const fn with_tweak(key: &'a [u8], tweak: &'a [u8]) -> Self

Uses key with an explicit tweak. Constant time.

Trait Implementations

impl<'a> Clone for ThreefishParamsRef<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for ThreefishParamsRef<'a>

impl Debug for ThreefishParamsRef<'_>

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

Writes public lengths, never key or tweak bytes. Constant time with respect to secret contents; timing depends on the formatter.

impl KeyParams for ThreefishParamsRef<'_>

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

Borrows the key without inspecting it. Constant time.

impl ThreefishParams for ThreefishParamsRef<'_>

fn tweak(&self) -> Option<&[u8]>

Borrows the optional tweak without inspecting it. Constant time.
