Struct Key 

pub struct Key { /* private fields */ }

Base key type backed by exact-size secret storage.

Implementations

impl Key

pub fn new(data: &[u8]) -> Self

Copy key bytes directly into exact-size owned storage.

The caller retains responsibility for clearing the source buffer. This constructor intentionally accepts a slice rather than taking a Vec: safe Rust cannot inspect or erase a vector’s spare capacity.

pub fn from_boxed_slice(data: Box<[u8]>) -> Self

Take ownership of an exact-size boxed key allocation.

pub fn from_slice(data: &[u8]) -> Self

Copy key bytes directly into exact-size owned storage.

pub fn new_zeros(len: usize) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn to_bytes_zeroizing_boxed(&self) -> ZeroizingBytes

Serialize into exact-size storage that clears itself on drop.

Trait Implementations

impl AsMut<[u8]> for Key

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u8]> for Key

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

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Key

fn clone(&self) -> Key

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Drop for Key

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 From<Box<[u8]>> for Key

fn from(data: Box<[u8]>) -> Self

Converts to this type from the input type.

impl SerializeSecret for Key

fn from_bytes(bytes: &[u8]) -> Result<Self>

Creates an object from a byte slice. Input should be zeroized after use.

fn to_bytes_zeroizing(&self) -> ZeroizingBytes

Converts the object to exact-size bytes that are zeroized on drop.

impl Zeroize for Key

fn zeroize(&mut self)

impl ZeroizeOnDrop for Key
