Enum MemoryAdvice 

pub enum MemoryAdvice {
    SetReadMostly,
    ClearReadMostly,
    SetPreferredLocation,
    ClearPreferredLocation,
    SetAccessedByDevice,
    ClearAccessedByDevice,
    BiasCached,
    BiasUncached,
}

Memory-advise hints applied to a shared/device USM range.

These mirror ze_memory_advice_t. The hints are pure metadata that the driver uses to steer page migration for shared USM; we model the intent here so a planner can validate and accumulate hints before issuing the device-gated zeCommandListAppendMemAdvise.

Variants

SetReadMostly

ZE_MEMORY_ADVICE_SET_READ_MOSTLY — pages are read far more than written.

ClearReadMostly

ZE_MEMORY_ADVICE_CLEAR_READ_MOSTLY.

SetPreferredLocation

ZE_MEMORY_ADVICE_SET_PREFERRED_LOCATION — pin to the device.

ClearPreferredLocation

ZE_MEMORY_ADVICE_CLEAR_PREFERRED_LOCATION.

SetAccessedByDevice

ZE_MEMORY_ADVICE_SET_ACCESSED_BY_DEVICE.

ClearAccessedByDevice

ZE_MEMORY_ADVICE_CLEAR_ACCESSED_BY_DEVICE.

BiasCached

ZE_MEMORY_ADVICE_BIAS_CACHED.

BiasUncached

ZE_MEMORY_ADVICE_BIAS_UNCACHED.

Implementations

impl MemoryAdvice

pub fn ze_value(self) -> u32

The ze_memory_advice_t enum value.

pub fn clearing_advice(self) -> Option<MemoryAdvice>

The advice that clears this one, if it is a set/clear pair.

Trait Implementations

impl Clone for MemoryAdvice

fn clone(&self) -> MemoryAdvice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MemoryAdvice

impl Debug for MemoryAdvice

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

Formats the value using the given formatter.

impl Eq for MemoryAdvice

impl PartialEq for MemoryAdvice

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