Struct BSTScatterTableHeapAllocator

#[repr(C)]
pub struct BSTScatterTableHeapAllocator { /* private fields */ }

An allocator implementation for the BSTScatterTable.

This allocator uses the Rust standard library’s alloc and dealloc functions to manage dynamic memory allocation, similar to C++’s malloc and free.

Implementations

impl BSTScatterTableHeapAllocator

pub const fn new() -> Self

Creates a new BSTScatterTableHeapAllocator instance with null entries.

Trait Implementations

impl Allocator for BSTScatterTableHeapAllocator

unsafe fn allocate_zeroed( &mut self, layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

Allocates a block of memory of the specified size in bytes.

Panics

Panics under the following conditions.

• If bytes_size is not a multiple of usize.

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

Deallocates a previously allocated block of memory.

fn get_entries(&self) -> *mut u8

Gets the current entries pointer.

fn set_entries(&mut self, entries: *mut u8)

Sets the entries pointer.

fn min_size() -> u32

Returns the minimum size that can be allocated by this allocator.

impl Debug for BSTScatterTableHeapAllocator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BSTScatterTableHeapAllocator

fn default() -> Self

Returns the “default value” for a type.
