Struct AlignedAllocator 

pub struct AlignedAllocator;

Aligned memory allocator for SIMD operations.

Zero-sized: holds no state. All calls delegate to the global allocator via std::alloc, which routes through whatever #[global_allocator] is registered (mimalloc when the mimalloc feature is enabled, otherwise the system allocator).

Implementations

impl AlignedAllocator

pub const fn new() -> Self

Construct a new allocator handle (zero cost).

pub unsafe fn alloc_aligned( &self, size: usize, alignment: usize, ) -> DomainResult<NonNull<u8>>

Allocate size bytes aligned to alignment (must be a power of two).

Returns a non-null pointer owned by the caller. The caller must deallocate it via AlignedAllocator::dealloc_aligned with the same Layout.

Safety

The returned pointer is valid for size bytes. The caller is responsible for ensuring the pointer is not used after deallocation.

pub unsafe fn realloc_aligned( &self, ptr: NonNull<u8>, old_layout: Layout, new_size: usize, ) -> DomainResult<NonNull<u8>>

Reallocate to new_size, preserving the original alignment.

Safety

ptr must have been returned by AlignedAllocator::alloc_aligned with old_layout. After this call, ptr is no longer valid — use the returned pointer instead.

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

Deallocate memory previously returned by AlignedAllocator::alloc_aligned.

Safety

ptr must have been returned by AlignedAllocator::alloc_aligned with exactly layout. Double-free or mismatched layout is undefined behavior.
