Struct ThreefishParamsOwned 

pub struct ThreefishParamsOwned { /* private fields */ }

An owned key with an optional owned tweak, both wiped on drop.

Available with the alloc feature. Construction takes the vectors without copying them. Nothing is validated here; the engine checks both lengths in init. Wiping does not erase copies held elsewhere. Debug prints the lengths, never the key or tweak.

Example

use tc_threefish::{ThreefishParams, ThreefishParamsOwned};

let params = ThreefishParamsOwned::with_tweak(vec![0x42; 32], vec![0x11; 16]);
assert_eq!(params.tweak(), Some(&[0x11; 16][..]));

Implementations

impl ThreefishParamsOwned

pub const fn new(key: Vec<u8>) -> Self

Uses key with Threefish’s all-zero tweak. Constant time: moves the vector without inspecting its bytes.

pub const fn with_tweak(key: Vec<u8>, tweak: Vec<u8>) -> Self

Uses key with an explicit tweak. Constant time: moves the vectors without inspecting their bytes.

Trait Implementations

impl Debug for ThreefishParamsOwned

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

Writes the key and tweak lengths, never their bytes. Constant time.

impl Drop for ThreefishParamsOwned

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 KeyParams for ThreefishParamsOwned

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

Returns the stored key without copying it. Constant time.

impl ThreefishParams for ThreefishParamsOwned

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

Returns the stored tweak without copying it. Constant time.

impl Zeroize for ThreefishParamsOwned

fn zeroize(&mut self)

Overwrites the key and tweak with zeros, leaving the key empty and the tweak absent. Constant time.
