Struct DefaultAllocator 

pub struct DefaultAllocator;

Default CPU allocator using system memory.

Implementations

impl DefaultAllocator

pub const fn new() -> Self

Creates a new default allocator.

pub const fn device(&self) -> Device

Returns the device this allocator is for.

pub fn allocate<T: Scalar>(&self, count: usize) -> Result<*mut T>

Allocates memory for count elements of type T.

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

Deallocates memory previously allocated.

Safety

The pointer must have been allocated by this allocator.

pub unsafe fn copy<T: Scalar>(&self, dst: *mut T, src: *const T, count: usize)

Copies memory from one location to another.

Safety

Both pointers must be valid for count elements.

pub unsafe fn zero<T: Scalar>(&self, ptr: *mut T, count: usize)

Fills memory with zeros.

Safety

The pointer must be valid for count elements.

pub fn total_memory(&self) -> usize

Returns the total memory available on the device.

pub fn free_memory(&self) -> usize

Returns the currently free memory on the device.
