Implementations

impl<Options: GlobalTlsfOptions> GlobalTlsf<Options>

pub const INIT: Self

The initializer.

Trait Implementations

impl<Options: GlobalTlsfOptions> CAlloc for GlobalTlsf<Options>

fn allocate(&self, layout: Layout) -> Option<NonNull<u8>>

Allocate a memory block.

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

Deallocate a previously allocated memory block.

unsafe fn reallocate(
    &self,
    ptr: NonNull<u8>,
    new_layout: Layout
) -> Option<NonNull<u8>>

Shrink or grow a previously allocated memory block.

impl<Options: GlobalTlsfOptions> GlobalAlloc for GlobalTlsf<Options>

unsafe fn alloc(&self, layout: Layout) -> *mut u8

Allocate memory as described by the given layout.

unsafe fn dealloc(&self, ptr: *mut u8, layout: Layout)

Deallocate the block of memory at the given ptr pointer with the given layout.

unsafe fn realloc(
    &self,
    ptr: *mut u8,
    layout: Layout,
    new_size: usize
) -> *mut u8

Shrink or grow a block of memory to the given new_size. The block is described by the given ptr pointer and layout.

unsafe fn alloc_zeroed(&self, layout: Layout) -> *mut u8

Behaves like alloc, but also ensures that the contents are set to zero before being returned.

impl<Options: GlobalTlsfOptions> Init for GlobalTlsf<Options>

const INIT: Self

Self’s default value.

impl<Options: GlobalTlsfOptions> Send for GlobalTlsf<Options>

impl<Options: GlobalTlsfOptions> Sync for GlobalTlsf<Options>
