Enum WipePosture 

#[non_exhaustive]
pub enum WipePosture {
    HardwareFence,
    CompilerFenceOnly,
}

Wipe-barrier posture for this build and target.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

HardwareFence

The target uses a native store-ordering hardware fence in addition to volatile writes and compiler fences.

This describes wipe-store ordering only. It is separate from CtGatePosture, which reports whether the constant-time result gate has a speculation barrier or only an ordering fence.

CompilerFenceOnly

The target uses volatile writes and compiler fences only.

Implementations

impl WipePosture

pub const fn as_str(self) -> &'static str

Returns the stable lowercase identifier for this wipe posture.

Trait Implementations

impl Clone for WipePosture

fn clone(&self) -> WipePosture

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WipePosture

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for WipePosture

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for WipePosture

fn eq(&self, other: &WipePosture) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
