Struct trallocator::Trallocator

pub struct Trallocator<A> { /* private fields */ }

A wapper over an allocator that allows tracebility

Implementations

impl<A> Trallocator<A>

pub const fn new(alloc: A) -> Self

Creates a new instance of the traceable allocator using an inner allocator

pub fn usage(&self) -> usize

Get the number of bytes used in the heap

pub fn borrow(&self) -> &A

Borrow the inner allocator. Note that using the inner allocator will prevent the allocation to be tracked. Should only be used to init the inner allocator

pub fn borrow_mut(&mut self) -> &mut A

Mutably borrow the inner allocator. Note that using the inner allocator will prevent the allocation to be tracked. Should only be used to init the inner allocator

Trait Implementations

impl<A: GlobalAlloc> GlobalAlloc for Trallocator<A>

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

Allocate memory as described by the given layout.

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

Deallocate the block of memory at the given ptr pointer with 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 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.
