Trait Implementations

impl Allocator for NonWorking

source

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. Read more

source

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. Read more

source

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

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

Deallocates the memory referenced by ptr. Read more

source

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. Read more

source

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. Read more

source

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. Read more

source

fn by_ref(&self) -> &Self

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

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

source
