Struct staging_tracking_allocator::TrackingAllocator

pub struct TrackingAllocator<A: GlobalAlloc>(pub A);

Tuple Fields

0: A

Implementations

impl<A: GlobalAlloc> TrackingAllocator<A>

pub unsafe fn start_tracking( &self, limit: Option<isize>, failure_handler: Option<Box<dyn Fn() + Send>>, )

Start tracking memory allocations and deallocations.

Safety

Failure handler is called with the allocator being in the locked state. Thus, no allocations or deallocations are allowed inside the failure handler; otherwise, a deadlock will occur.

pub fn end_tracking(&self) -> isize

End tracking and return the peak allocation value in bytes (as isize). Peak allocation value is not guaranteed to be neither non-zero nor positive.

Trait Implementations

impl<A: GlobalAlloc> GlobalAlloc for TrackingAllocator<A>

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

Allocate memory as described by the given 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.

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

Deallocate 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

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