Struct MTL4TimestampGranularity 

#[repr(transparent)]
pub struct MTL4TimestampGranularity(pub NSInteger);

Available on crate feature MTL4Counters only.

Provides a hint to the system about the desired accuracy when writing GPU counter timestamps.

Pass these values to MTL4ComputeCommandEncoder/writeTimestampWithGranularity:intoHeap:atIndex: and MTL4RenderCommandEncoder/writeTimestampWithGranularity:afterStage:intoHeap:atIndex: to control the desired accurracy of the counter sampling operation.

Implementations

impl MTL4TimestampGranularity

pub const Relaxed: Self

A minimally-invasive timestamp which may be less precise.

Using this granularity incurs in the lowest overhead, at the cost of precision. For example, it may sample at command encoder boundaries.

pub const Precise: Self

A timestamp as precise as possible.

Using this granularity may incur in a performance penalty, for example, it may cause splitting of command encoders.

Trait Implementations

impl Clone for MTL4TimestampGranularity

fn clone(&self) -> MTL4TimestampGranularity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MTL4TimestampGranularity

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

Formats the value using the given formatter.

impl Encode for MTL4TimestampGranularity

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for MTL4TimestampGranularity

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 MTL4TimestampGranularity

fn cmp(&self, other: &MTL4TimestampGranularity) -> 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 MTL4TimestampGranularity

fn eq(&self, other: &MTL4TimestampGranularity) -> 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 MTL4TimestampGranularity

fn partial_cmp(&self, other: &MTL4TimestampGranularity) -> 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.

impl RefEncode for MTL4TimestampGranularity

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.
