Struct KeyRef 

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

A borrowed key slice with no allocation or copying.

The caller owns the bytes and is responsible for wiping them. Dropping this view does not modify the key. The engine validates the key length.

Implementations

impl<'a> KeyRef<'a>

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

Borrows key bytes without validating their length. Constant time: does not inspect the bytes.

Trait Implementations

impl KeyParams for KeyRef<'_>

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

Returns the stored key bytes without copying them. Constant time: does not inspect key contents.
