Expand description

Trait to zeroize a memory buffer. Trait for securely erasing types from memory

Required methods

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

Implementations on Foreign Types

impl Zeroize for __m128d

Implement Zeroize on arrays of types that impl Zeroize

source

impl Zeroize for __m128

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

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().

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

“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.
