Enum BackendPolicy 

#[non_exhaustive]
pub enum BackendPolicy {
    ScalarExecutionOnly,
    SimdFeatureDisabled,
    NoDetectedSimdCandidate,
    HighAssuranceScalarOnly,
}

Deployment policy for runtime backend assertions.

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.

ScalarExecutionOnly

Require encode/decode execution to use the scalar backend.

SimdFeatureDisabled

Require the crate to be built without the simd feature.

NoDetectedSimdCandidate

Require no SIMD candidate to be visible to this build and target.

HighAssuranceScalarOnly

Require scalar execution, the simd feature disabled, no detected SIMD candidate, and the unsafe boundary enforced.

Implementations

impl BackendPolicy

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

Returns the stable lowercase identifier for this policy.

assert_eq!(
    base64_ng::runtime::BackendPolicy::HighAssuranceScalarOnly.as_str(),
    "high-assurance-scalar-only",
);

Trait Implementations

impl Clone for BackendPolicy

fn clone(&self) -> BackendPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendPolicy

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

Formats the value using the given formatter.

impl Display for BackendPolicy

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

Formats the value using the given formatter.

impl PartialEq for BackendPolicy

fn eq(&self, other: &BackendPolicy) -> 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.
