Trait Implementations

impl Allocator for NonWorking

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

🔬This is a nightly-only experimental API. (allocator_api)

Attempts to allocate a block of memory.

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

🔬This is a nightly-only experimental API. (allocator_api)

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

unsafe fn deallocate(&self, _ptr: NonNull<u8>, _layout: Layout)

🔬This is a nightly-only experimental API. (allocator_api)

Deallocates the memory referenced by ptr.

unsafe fn grow(
    &self,
    _ptr: NonNull<u8>,
    _old_layout: Layout,
    _new_layout: Layout
) -> Result<NonNull<[u8]>, AllocError>

🔬This is a nightly-only experimental API. (allocator_api)

Attempts to extend the memory block.

unsafe fn grow_zeroed(
    &self,
    _ptr: NonNull<u8>,
    _old_layout: Layout,
    _new_layout: Layout
) -> Result<NonNull<[u8]>, AllocError>

🔬This is a nightly-only experimental API. (allocator_api)

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

unsafe fn shrink(
    &self,
    _ptr: NonNull<u8>,
    _old_layout: Layout,
    _new_layout: Layout
) -> Result<NonNull<[u8]>, AllocError>

🔬This is a nightly-only experimental API. (allocator_api)

Attempts to shrink the memory block.

fn by_ref(&self) -> &Selfwhere
    Self: Sized,

🔬This is a nightly-only experimental API. (allocator_api)

Creates a “by reference” adapter for this instance of Allocator.

impl Clone for NonWorking

fn clone(&self) -> NonWorking

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NonWorking

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

Formats the value using the given formatter.

impl Default for NonWorking

const fn default() -> Self

Returns the “default value” for a type.

impl Fallbackable for NonWorking

unsafe fn has_allocated(&self, _ptr: NonNull<u8>, _layout: Layout) -> bool

Safety

fn allows_fallback(&self, _layout: Layout) -> bool
