Struct GlobalAllocator

pub struct GlobalAllocator;

A global allocator for our program.

Trait Implementations

impl Allocator for GlobalAllocator

fn allocate(&self, layout: Layout) -> Option<NonNull<u8>>

unsafe fn deallocate(&self, pointer: *mut u8, layout: Layout)

unsafe fn reallocate( &self, pointer: *mut u8, oldSize: usize, layout: Layout, ) -> Option<NonNull<u8>>

unsafe fn allocate_aligned(&self, layout: Layout) -> Option<NonNull<u8>>

unsafe fn deallocate_aligned(&self, pointer: *mut u8, layout: Layout)

impl Clone for GlobalAllocator

fn clone(&self) -> GlobalAllocator

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl GlobalAlloc for GlobalAllocator

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

Allocates memory as described by the given layout.

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

Deallocates 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

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.
