Struct opencl3::memory::Buffer

pub struct Buffer<T> { /* fields omitted */ }

An OpenCL buffer.
Implements the Drop trait to call release_mem_object when the object is dropped.

Implementations

impl<T> Buffer<T>

pub fn new(buffer: cl_mem) -> Buffer<T>

pub fn create(
    context: &Context,
    flags: cl_mem_flags,
    count: size_t,
    host_ptr: *mut c_void
) -> Result<Buffer<T>>

Create a Buffer for a context.

• context - a valid OpenCL context.
• flags - a bit-field used to specify allocation and usage information about the image memory object being created, see: Memory Flags.
• count - the number of T objects to be allocated.
• host_ptr - a pointer to the buffer data that may already be allocated by the application.

returns a Result containing the new OpenCL buffer object or the error code from the OpenCL C API function.

pub fn create_from_gl_buffer(
    context: &Context,
    flags: cl_mem_flags,
    bufobj: gl_uint
) -> Result<Buffer<T>>

Create an OpenCL buffer object for a context from an OpenGL buffer.

• context - a valid OpenCL context created from an OpenGL context.
• flags - a bit-field used to specify allocation and usage information about the image memory object being created, see: Memory Flags.
• bufobj - the OpenGL buffer.

returns a Result containing the new OpenCL buffer object or the error code from the OpenCL C API function.

pub fn create_sub_buffer(
    &self,
    flags: cl_mem_flags,
    origin: usize,
    count: usize
) -> Result<Buffer<T>>

Create an new OpenCL buffer object from an existing buffer object.
See: SubBuffer Attributes.

• flags - a bit-field used to specify allocation and usage information about the sub-buffer memory object being created, see: Memory Flags.
• origin - the offset in number of objects of type .
• count - the size of the sub-buffer in number of objects of type .

returns a Result containing the new OpenCL buffer object or the error code from the OpenCL C API function.
