Trait Implementations

impl Allocator for Global

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

Attempts to allocate a block of memory.

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

Behaves like allocate, but also ensures that the returned memory is zero-initialized.

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

Deallocates the memory referenced by ptr.

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

Attempts to extend the memory block.

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

Behaves like grow, but also ensures that the new contents are set to zero before being returned.

impl Clone for Global

fn clone(&self) -> Global

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl Default for Global

fn default() -> Global

Returns the “default value” for a type.

impl TryFromIteratorIn<Value, Global> for Stack

fn try_from_iter_in<T: IntoIterator<Item = Value>>( iter: T, alloc: Global ) -> Result<Self>

Creates a value from an iterator within an allocator.
