Struct SecretValue 

pub struct SecretValue<L: ArrayLength>(/* private fields */);

Represents a secret value of a fixed length that is zeroized on drop. Secret values are always compared in constant time. The default value is all zeroes.

Implementations

impl<L: ArrayLength> SecretValue<L>

pub const LENGTH: usize = L::USIZE

Length of the secret value in bytes.

Trait Implementations

impl<L: ArrayLength> AsMut<[u8]> for SecretValue<L>

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

impl<L: ArrayLength> AsRef<[u8]> for SecretValue<L>

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

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