Struct MTLCPUCacheMode 

#[repr(transparent)]
pub struct MTLCPUCacheMode(pub NSUInteger);

Available on crate feature MTLResource only.

Describes what CPU cache mode is used for the CPU’s mapping of a texture resource.

The default cache mode for the system.

Write combined memory is optimized for resources that the CPU will write into, but never read. On some implementations, writes may bypass caches avoiding cache pollution, and reads perform very poorly.

Applications should only investigate changing the cache mode if writing to normally cached buffers is known to cause performance issues due to cache pollution, as write combined memory can have surprising performance pitfalls. Another approach is to use non-temporal stores to normally cached memory (STNP on ARMv8, mm_stream* on x86_64).

Trait Implementations

impl Clone for MTLCPUCacheMode

fn clone(&self) -> MTLCPUCacheMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MTLCPUCacheMode

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

Formats the value using the given formatter.

impl Encode for MTLCPUCacheMode

const ENCODING: Encoding = NSUInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for MTLCPUCacheMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for MTLCPUCacheMode

fn cmp(&self, other: &MTLCPUCacheMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MTLCPUCacheMode

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

impl PartialOrd for MTLCPUCacheMode

fn partial_cmp(&self, other: &MTLCPUCacheMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
