Struct ProfilingAllocator 

pub struct ProfilingAllocator<const CPU_FREQ: u32 = 99>;

A profiling allocator that wraps the system allocator.

The const generic CPU_FREQ specifies the CPU sampling frequency in Hz. Set to 0 to disable CPU profiling.

When the heap feature is enabled, this allocator captures allocation and deallocation events along with stack traces. CPU profiling (if enabled) starts automatically on the first allocation.

When profiling features are disabled, it’s a zero-cost passthrough.

Implementations

impl<const CPU_FREQ: u32> ProfilingAllocator<CPU_FREQ>

pub const fn new() -> Self

Trait Implementations

impl<const CPU_FREQ: u32> Default for ProfilingAllocator<CPU_FREQ>

fn default() -> Self

Returns the “default value” for a type.

impl<const CPU_FREQ: u32> GlobalAlloc for ProfilingAllocator<CPU_FREQ>

unsafe fn alloc(&self, layout: Layout) -> *mut u8

Allocates memory as described by the given layout.

unsafe fn dealloc(&self, ptr: *mut u8, _layout: Layout)

Deallocates the block of memory at the given ptr pointer with the given layout.

unsafe fn realloc( &self, ptr: *mut u8, _layout: Layout, new_size: usize, ) -> *mut u8

Shrinks or grows a block of memory to the given new_size in bytes. The block is described by the given ptr pointer and layout.

unsafe fn alloc_zeroed(&self, layout: Layout) -> *mut u8

Behaves like alloc, but also ensures that the contents are set to zero before being returned.
