Struct Freelist

pub struct Freelist<Limit: LimitParam, A: Allocator + Clone> { /* private fields */ }

Implementations

impl<Limit: LimitParam, A: Allocator + Clone> Freelist<Limit, A>

pub const fn new( layout: Layout, tolerance: Layout, limit: Limit, base: A, ) -> Self

pub const unsafe fn new_unchecked( layout: Layout, tolerance: Layout, limit: Limit, base: A, ) -> Self

Safety

Arguments should satisfy tolerance.size() <= layout.size() && tolerance.align() <= layout.align(), and layout.size() >= MIN_LAYOUT_SIZE && layout.align() >= MIN_LAYOUT_ALIGN.

Trait Implementations

impl<Limit: LimitParam, A: Allocator + Clone> Allocator for Freelist<Limit, 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<Limit: LimitParam, A: Fallbackable + Clone> Fallbackable for Freelist<Limit, A>

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

Safety

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