Struct blink_alloc::LocalBlinkAlloc

pub struct LocalBlinkAlloc<'a, A: Allocator = Global> { /* private fields */ }

Thread-local proxy for SyncBlinkAlloc.

Using proxy can yield better performance when it is possible to create proxy once to use for many allocations.

See SyncBlinkAlloc::local for more details.

Implementations

impl<A> LocalBlinkAlloc<'_, A>where A: Allocator,

pub fn reset(&mut self)

Resets this allocator, deallocating all chunks except the last one. Last chunk will be reused. With steady memory usage after few iterations chunk size should be sufficient for all allocations between resets.

Trait Implementations

impl<A> Allocator for &mut LocalBlinkAlloc<'_, A>where A: Allocator,

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.

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

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

Deallocates the memory referenced by ptr.

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 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<A> Allocator for LocalBlinkAlloc<'_, A>where A: Allocator,

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.

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

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

Deallocates the memory referenced by ptr.

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

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

🔬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<A> BlinkAllocator for LocalBlinkAlloc<'_, A>where A: Allocator,

fn reset(&mut self)

Resets allocator potentially invalidating all allocations made from this instance. This is no-op if allocator is Clone (typically shared reference to blink-allocator).

impl<A> Drop for LocalBlinkAlloc<'_, A>where A: Allocator,

fn drop(&mut self)

Executes the destructor for this type.
