Initialize a protected container type for a slice of elements.

Required Associated Types

type Item

The type of the elements contained in the slice.

Provided Methods

fn init_slice<F>(len: usize, f: F) -> Self

where F: FnOnce(SecureRef<&mut [Self::Item]>), Self::Item: Copy + FillBytes,

For a concrete type implementing FillBytes, initialize a slice of length len with the standard indicator value and call the closure f with a mutable reference to the slice before applying protections.

fn init_default_slice<F>(len: usize, f: F) -> Self

where F: FnOnce(SecureRef<&mut [Self::Item]>), Self::Item: Default,

Initialize with a slice of length len containing the default value for Self::Item, and call the closure f with a mutable reference to the slice before applying protections.

fn init_random_slice<F>(len: usize, rng: impl RngCore, f: F) -> Self

where F: FnOnce(SecureRef<&mut [Self::Item]>), Self::Item: Copy + FillBytes,

Initialize with a randomized slice of length len, and call the closure f with a mutable reference to the slice before applying protections.

fn init_take_slice<F>(from: &mut [Self::Item], f: F) -> Self

where F: FnOnce(SecureRef<&mut [Self::Item]>), Self::Item: DefaultIsZeroes,

Initialize by copying the slice from and zeroizing the existing copy. Call the closure f with a mutable reference to the contained slice before applying protections.

fn random_slice(len: usize, rng: impl RngCore) -> Self

where Self::Item: Copy + FillBytes,

Create a new protected instance containing a random slice of length len.

fn take_slice(from: &mut [Self::Item]) -> Self

where Self::Item: DefaultIsZeroes,

Create a new protected slice instance by copying and zeroizing an existing slice.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
