Struct Spill

pub struct Spill<'a, A> { /* private fields */ }

An allocator which may represent either a fixed allocation or a dynamic allocation with an allocator instance A.

Trait Implementations

impl<A: Allocator> Allocator for Spill<'_, A>

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

Try to allocate a slice of memory within this allocator instance, returning the new allocation.

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

Release an allocation produced by this allocator.

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

Try to allocate a slice of memory within this allocator instance, returning the new allocation. The memory will be initialized with zeroes.

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

Try to extend the size of an allocation to accomodate a new, larger layout.

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

Try to extend the size of an allocation to accomodate a new, larger layout. Fill the extra capacity with zeros.

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

Try to reduce the size of an allocation to accomodate a new, smaller layout.

fn by_ref(&self) -> &Self

where Self: Sized,

Obtain a reference to this allocator type.

impl<'a, A: AllocatorDefault> AllocatorDefault for Spill<'a, A>

const DEFAULT: Self = _

The constant initializer for this allocator.

impl<'a, A: Default + Allocator> Clone for Spill<'a, A>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, A: Debug> Debug for Spill<'a, A>

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

Formats the value using the given formatter.

impl<A: Default + Allocator> Default for Spill<'_, A>

fn default() -> Self

Returns the “default value” for a type.
