Struct CounterHeap 

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

A heap for GPU performance counters.

C++ equivalent: MTL4::CounterHeap

CounterHeap provides storage for GPU performance counters and timestamps.

Implementations

impl CounterHeap

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

Create a CounterHeap from a raw pointer.

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

Get the raw pointer.

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

Get the label.

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

pub fn set_label(&self, label: &str)

Set the label.

C++ equivalent: void setLabel(const NS::String*)

pub fn heap_type(&self) -> CounterHeapType

Get the counter heap type.

C++ equivalent: CounterHeapType type() const

pub fn count(&self) -> UInteger

Get the counter count.

C++ equivalent: NS::UInteger count() const

pub fn invalidate_counter_range(&self, location: UInteger, length: UInteger)

Invalidate a range of counters.

C++ equivalent: void invalidateCounterRange(NS::Range)

pub fn resolve_counter_range_raw( &self, location: UInteger, length: UInteger, ) -> *mut c_void

Resolve a range of counters and return the data.

C++ equivalent: NS::Data* resolveCounterRange(NS::Range)

Returns the raw data pointer. Caller is responsible for interpreting the data based on the counter heap type.
