Struct Counter 

pub struct Counter(/* private fields */);

A single GPU performance counter.

C++ equivalent: MTL::Counter

Counters are obtained from a CounterSet and represent individual performance metrics that can be sampled.

Implementations

impl Counter

pub unsafe fn from_raw(ptr: *mut c_void) -> Option<Self>

Create from a raw pointer.

Safety

The pointer must be a valid Metal counter.

pub fn as_raw(&self) -> *mut c_void

Get the raw pointer.

pub fn name(&self) -> Option<String>

Get the name of this counter.

C++ equivalent: NS::String* name() const

Trait Implementations

impl Clone for Counter

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Counter

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

Formats the value using the given formatter.

impl Drop for Counter

fn drop(&mut self)

Executes the destructor for this type.

impl Referencing for Counter

fn as_ptr(&self) -> *const c_void

Get the raw pointer to the Objective-C object.

fn as_mut_ptr(&self) -> *mut c_void

Get the raw mutable pointer to the Objective-C object.

fn retain(&self) -> Self

where Self: Clone,

Retain the object, incrementing its reference count.

fn release(&self)

Release the object, decrementing its reference count.

fn autorelease(&self) -> Self

where Self: Clone,

Autorelease the object.

fn retain_count(&self) -> usize

Get the retain count of the object.
