Trait Implementations§

impl GlobalAlloc for CountingAllocator

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

Allocates memory as described by the given layout. Read more

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. Read more

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. Read more

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

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