Struct Tracking 

pub struct Tracking<A>(pub A);

Global allocator wrapper that tracks live bytes and a resettable high-water mark.

Counters use relaxed ordering: they are diagnostics, not synchronisation, and the cost must stay near zero on the allocation path.

0: A

Trait Implementations

impl<A: GlobalAlloc> GlobalAlloc for Tracking<A>

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.
