pub struct SpectreMitigation;
Expand description

Spectre v1 mitigation helpers.

Implementations§

Source§

impl SpectreMitigation

Source

pub fn speculation_barrier()

Insert a speculation barrier after a bounds check.

On x86_64 this emits LFENCE, on AArch64 CSDB, on RISC-V FENCE.

Source

pub fn safe_array_access<T: Copy + Default>(arr: &[T], index: usize) -> T

Bounds-checked array access with speculation barrier.

Returns the value at index if in bounds, otherwise returns the default value. Always inserts a speculation barrier after the check.
