pub struct Affix<Alloc, Prefix = (), Suffix = ()> {
    pub alloc: Alloc,
    // some fields omitted
}

Fields

alloc: Alloc

Methods

impl<Alloc, Prefix, Suffix> Affix<Alloc, Prefix, Suffix>

pub const fn new(alloc: Alloc) -> Self

pub unsafe fn prefix(ptr: NonNull<u8>, layout: Layout) -> NonNull<Prefix>

Safety

• ptr must denote a block of memory [currently allocated] via this allocator, and
• layout must [fit] that block of memory.

pub unsafe fn suffix(ptr: NonNull<u8>, layout: Layout) -> NonNull<Suffix>

Safety

• ptr must denote a block of memory [currently allocated] via this allocator, and
• layout must [fit] that block of memory.

    Alloc: AllocRef, 

fn alloc(
    &mut self,
    layout: Layout,
    init: AllocInit
) -> Result<MemoryBlock, AllocErr>

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

Attempts to allocate a block of memory.

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

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

Deallocates the memory referenced by ptr.

unsafe fn grow(
    &mut self,
    ptr: NonNull<u8>,
    old_layout: Layout,
    new_size: usize,
    placement: ReallocPlacement,
    init: AllocInit
) -> Result<MemoryBlock, AllocErr>

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

Attempts to extend the memory block.

unsafe fn shrink(
    &mut self,
    ptr: NonNull<u8>,

) -> Result<MemoryBlock, AllocErr>

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

Attempts to shrink the memory block.

fn by_ref(&mut self) -> &mut Self

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

Creates a "by reference" adaptor for this instance of AllocRef.
