Methods from Deref<Target = Buffer<'a, T, D, S>>

pub fn copy(&self) -> Buffer<'a, T, (), ()>where T: Copy,

pub fn item(&self) -> Twhere T: Copy,

Used if the Buffer contains only a single value. By derefencing this Buffer, you obtain this value as well (which is probably preferred).

use custos::Buffer;

let x: Buffer<f32, _> = 7f32.into();
assert_eq!(*x, 7.);
assert_eq!(x.item(), 7.);

pub fn read_to_vec(&self) -> Vec<T, Global>where D: Read<T, D, S>, T: Default + Clone,

Reads the contents of the buffer and writes them into a vector. If it is certain whether a CPU, or an unified CPU + OpenCL Buffer, is used, calling .as_slice() (or deref/mut to &/mut [&T]) is probably preferred.

Example

use custos::{CPU, Buffer};

let device = CPU::new();
let buf = Buffer::from((&device, [1, 2, 3, 4]));

assert_eq!(buf.read_to_vec(), vec![1, 2, 3, 4]);

pub fn write(&mut self, data: &[T])where T: Clone, D: WriteBuf<T, D, S>,

Writes a slice to the Buffer. With a CPU buffer, the slice is just copied to the slice of the buffer.

pub fn len(&self) -> usize

Returns the number of elements contained in Buffer.

Example

use custos::{CPU, Buffer};

let device = CPU::new();
let a = Buffer::<i32, _>::new(&device, 10);
assert_eq!(a.len(), 10)

pub unsafe fn shallow(&self) -> Buffer<'a, T, D, S>where <D as Device>::Ptr<T, S>: ShallowCopy,

Creates a shallow copy of &self.

Safety

Itself, this function does not need to be unsafe. However, declaring this function as unsafe highlights the violation of creating two or more owners for one resource. Furthermore, the resulting Buffer can outlive self.

pub unsafe fn shallow_or_clone(&self) -> Buffer<'a, T, D, S>where <D as Device>::Ptr<T, S>: ShallowCopy, T: Clone, D: CloneBuf<'a, T, S>,

Returns a shallow copy of &self, if the realloc feature is deactivated. If the realloc feature is activated, it returns a deep copy / clone.

Safety

Itself, this function does not need to be unsafe. However, declaring this function as unsafe highlights the violation of possibly creating two or more owners for one resource. Furthermore, the resulting Buffer can outlive self.

pub fn id(&self) -> Ident

pub fn as_dims<'b, O>(&self) -> &Buffer<'b, T, D, O>where O: Shape,

pub fn as_dims_mut<'b, O>(&mut self) -> &mut Buffer<'b, T, D, O>where O: Shape,

pub fn ptrs(&self) -> (*const T, *mut c_void, u64)

Returns all types of pointers. (host, OpenCL, CUDA)

pub fn ptrs_mut(&mut self) -> (*mut T, *mut c_void, u64)

Returns all types of pointers. (host, OpenCL, CUDA)

pub fn is_empty(&self) -> bool

Returns true if Buffer is created without a slice.

Example

use custos::{CPU, Buffer};

let a = Buffer::<i32, ()>::from(5);
assert!(a.is_empty())

pub fn clear(&mut self)where D: ClearBuf<T, D, ()>,

Sets all elements in Buffer to the default value.

pub fn cl_ptr(&self) -> *mut c_void

pub fn cu_ptr(&self) -> u64

Returns a non null CUDA pointer

pub fn as_slice(&self) -> &[T]

Returns a CPU slice. This does not work with CUDA or raw OpenCL buffers.

pub fn as_mut_slice(&mut self) -> &mut [T]

Returns a mutable CPU slice.

pub fn host_ptr(&self) -> *const T

Returns a non null host pointer

pub fn host_ptr_mut(&mut self) -> *mut T

Returns a non null host pointer
