pub struct Alloc { /* private fields */ }

Implementations

impl Alloc

pub const fn new() -> Self

impl Alloc

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

Safety

Layout must be valid.

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

Safety

Layout must be valid.

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

Safety

Layout and pointer must be valid.

Alignment must match of original allocation.

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

Safety

Pointer must be valid.

pub unsafe fn size(&self, ptr: *mut u8) -> usize

Safety

Pointer must be valid.

Trait Implementations

impl Clone for Alloc

fn clone(&self) -> Alloc

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Alloc

fn default() -> Self

Returns the “default value” for a type.

impl GlobalAlloc for Alloc

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

Allocate memory as described by the given layout.

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

Deallocate 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

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