Struct Allocator

#[repr(C)]
pub struct Allocator<'a> {
    pub zalloc: alloc_func,
    pub zfree: free_func,
    pub opaque: voidpf,
    pub _marker: PhantomData<&'a ()>,
}

Fields

zalloc: alloc_func

zfree: free_func

opaque: voidpf

_marker: PhantomData<&'a ()>

Implementations

impl Allocator<'static>

pub const RUST: Self = _

pub const C: Self = _

impl Allocator<'_>

pub fn allocate_layout(&self, layout: Layout) -> *mut c_void

pub fn allocate_raw<T>(&self) -> Option<*mut T>

pub fn allocate_slice_raw<T>(&self, len: usize) -> Option<*mut T>

pub fn allocate_zeroed(&self, len: usize) -> *mut u8

pub unsafe fn deallocate<T>(&self, ptr: *mut T, len: usize)

Panics

• when len is 0

Safety

• ptr must be allocated with this allocator
• len must be the number of Ts that are in this allocation

Trait Implementations

impl<'a> Clone for Allocator<'a>

fn clone(&self) -> Allocator<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
