Trait Zeroize

pub trait Zeroize {
    // Required method
    fn zeroize(&mut self);
}

Trait for securely erasing values from memory.

Required Methods

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl<Z> Zeroize for Option<Z>

where Z: Zeroize,

fn zeroize(&mut self)

impl<Z> Zeroize for [Z]

where Z: DefaultIsZeroes,

Impl Zeroize on slices of types that can be zeroized with Default.

This impl can eventually be optimized using an memset intrinsic, such as core::intrinsics::volatile_set_memory. For that reason the blanket impl on slices is bounded by DefaultIsZeroes.

To zeroize a mut slice of Z: Zeroize which does not impl DefaultIsZeroes, call iter_mut().zeroize().

fn zeroize(&mut self)

impl<Z> Zeroize for Box<[Z]>

where Z: Zeroize,

fn zeroize(&mut self)

Unlike Vec, Box<[Z]> cannot reallocate, so we can be sure that we are not leaving values on the heap.

impl<Z> Zeroize for Vec<Z>

where Z: Zeroize,

fn zeroize(&mut self)

“Best effort” zeroization for Vec.

Ensures the entire capacity of the Vec is zeroed. Cannot ensure that previous reallocations did not leave values on the heap.

impl<Z> Zeroize for PhantomData<Z>

PhantomData is always zero sized so provide a Zeroize implementation.

fn zeroize(&mut self)

impl<Z> Zeroize for Wrapping<Z>

where Z: Zeroize,

fn zeroize(&mut self)

impl<Z> Zeroize for [MaybeUninit<Z>]

Impl Zeroize on slices of MaybeUninit types.

This impl can eventually be optimized using an memset intrinsic, such as core::intrinsics::volatile_set_memory.

This fills the slice with zeroes.

Note that this ignore invariants that Z might have, because MaybeUninit removes all invariants.

fn zeroize(&mut self)

impl<Z, const N: usize> Zeroize for [Z; N]

where Z: Zeroize,

Impl Zeroize on arrays of types that impl Zeroize.
