Enum PrefetchLocality 

pub enum PrefetchLocality {
    NonTemporal,
    Low,
    Medium,
    High,
}

Prefetch locality hint levels.

These correspond to the x86 prefetch instruction locality hints. Higher locality means the data is expected to be accessed more times and should be kept in closer cache levels.

Variants

NonTemporal

Non-temporal: Data will be accessed once and then not reused. Minimizes cache pollution.

Low

Low locality: Data will be accessed a few times. Kept in L3 cache.

Medium

Medium locality: Data will be accessed several times. Kept in L2 cache.

High

High locality: Data will be accessed many times. Kept in L1 cache.

Trait Implementations

impl Clone for PrefetchLocality

fn clone(&self) -> PrefetchLocality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrefetchLocality

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

Formats the value using the given formatter.

impl PartialEq for PrefetchLocality

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