Struct SimdAllocator 

pub struct SimdAllocator { /* private fields */ }

SIMD-optimized allocator with alignment guarantees

Implementations

impl SimdAllocator

pub const fn new() -> Self

Create a new SIMD allocator with default 32-byte alignment (AVX2)

pub const fn with_alignment(alignment: usize) -> Self

Create a new SIMD allocator with custom alignment

pub fn stats(&self) -> &AllocatorStats

Get allocator statistics

pub fn allocate_simd<T>(&self, count: usize) -> Option<NonNull<T>>

Allocate aligned memory for SIMD operations

pub unsafe fn deallocate_simd<T>(&self, ptr: NonNull<T>, count: usize)

Deallocate SIMD-aligned memory previously allocated by allocate_simd.

Safety

ptr must have been allocated by this allocator with count elements of type T, and must not be used after this call.

pub fn allocate_zeroed_simd<T>(&self, count: usize) -> Option<NonNull<T>>

where T: Copy,

Allocate zero-initialized SIMD memory

pub unsafe fn reallocate_simd<T>( &self, ptr: NonNull<T>, old_count: usize, new_count: usize, ) -> Option<NonNull<T>>

Reallocate SIMD memory with preserved alignment.

Safety

ptr must have been allocated by this allocator with old_count elements of type T. The returned pointer (if Some) replaces ptr, which must not be used after this call.

Trait Implementations

impl Default for SimdAllocator

fn default() -> Self

Returns the “default value” for a type.

impl GlobalAlloc for SimdAllocator

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

Allocates memory as described by the given layout.

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

Deallocates the block of memory at the given ptr pointer with the given 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.

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

Shrinks or grows a block of memory to the given new_size in bytes. The block is described by the given ptr pointer and layout.
