Struct Global 

pub struct Global;

This is basically a wrapper around the std global allocator APIs.

See: https://doc.rust-lang.org/std/alloc/struct.Global.html

It has the same name as Global since the allocator APIs are not stabilized yet. When stabilized this will be just removed. Rust’s Global will be exported for backwards compatibility.

Trait Implementations

impl AltAllocator for Global

fn allocate(&self, layout: Layout) -> Result<NonNull<[u8]>, AllocError>

Allocates a chunk of memory with the given layout.

fn allocate_zeroed(&self, layout: Layout) -> Result<NonNull<[u8]>, AllocError>

Allocates just like allocate but also zeroes the memory.

unsafe fn deallocate(&self, ptr: NonNull<u8>, layout: Layout)

Deallocates the chunk of memory pointed at byptr

unsafe fn grow( &self, old_ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

Grows the memory pointed at by old_ptr to the new layout.

unsafe fn grow_zeroed( &self, old_ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

Behaves just like grow but the new memory will be zeroed.

unsafe fn shrink( &self, old_ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

Shrinks the memory pointed at by old_ptr to the new layout. The new layout must be smaller than the old layout.

impl Clone for Global

fn clone(&self) -> Global

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Global

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Copy for Global
