Struct AlignmentCorrectorAllocator 

pub struct AlignmentCorrectorAllocator<I, O, A: Allocator> { /* private fields */ }

Handling correcting the alignment fed into the inner allocator.

Implementations

impl<I, O, A: Allocator> AlignmentCorrectorAllocator<I, O, A>

pub unsafe fn new(ptr: NonNull<O>, allocator: A) -> Self

Create new AlignmentCorrectorAllocator.

Safety

The ptr must be allocated with the allocator in the alignment of I.

pub fn new_null(allocator: A) -> Self

Create a new AlignmentCorrectorAllocator that acts the same as the allocator fed into it.

pub fn is_null(&self) -> bool

Is the AlignmentCorrectorAllocator no longer doing anything?

pub fn into_inner(self) -> Result<A, Self>

If the AlignmentCorrectorAllocator is no longer doing anything, returns the inner allocator

Trait Implementations

impl<I, O, A: Allocator> Allocator for AlignmentCorrectorAllocator<I, O, A>

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) -> &Self

where Self: Sized,

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

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

impl<I: Debug, O: Debug, A: Debug + Allocator> Debug for AlignmentCorrectorAllocator<I, O, A>

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

Formats the value using the given formatter.
