Constant methods for core::Buffer

Required Methods§

Source

fn as_raw_Buffer(&self) -> *const c_void

Provided Methods§

Source

fn copy_to(&self, arr: &mut impl ToOutputArray) -> Result<()>

Copies from OpenGL buffer to host/device memory or another OpenGL buffer object.

§Parameters
  • arr: Destination array (host or device memory, can be Mat , cuda::GpuMat , std::vector or ogl::Buffer ).
Source

fn copy_to_1( &self, arr: &mut impl ToOutputArray, stream: &mut impl StreamTrait, ) -> Result<()>

Copies from OpenGL buffer to host/device memory or another OpenGL buffer object.

§Parameters
  • arr: Destination array (host or device memory, can be Mat , cuda::GpuMat , std::vector or ogl::Buffer ).
§Overloaded parameters
Source

fn clone(&self, target: Buffer_Target, auto_release: bool) -> Result<Buffer>

Creates a full copy of the buffer object and the underlying data.

§Parameters
  • target: Buffer usage for destination buffer.
  • autoRelease: Auto release mode for destination buffer.
§C++ default parameters
  • target: ARRAY_BUFFER
  • auto_release: false
Source

fn clone_def(&self) -> Result<Buffer>

Creates a full copy of the buffer object and the underlying data.

§Parameters
  • target: Buffer usage for destination buffer.
  • autoRelease: Auto release mode for destination buffer.
§Note

This alternative version of BufferTraitConst::clone function uses the following default values for its arguments:

  • target: ARRAY_BUFFER
  • auto_release: false
Source

fn bind(&self, target: Buffer_Target) -> Result<()>

Binds OpenGL buffer to the specified buffer binding point.

§Parameters
  • target: Binding point. See cv::ogl::Buffer::Target .
Source

fn rows(&self) -> Result<i32>

Source

fn cols(&self) -> Result<i32>

Source

fn size(&self) -> Result<Size>

Source

fn empty(&self) -> Result<bool>

Source

fn typ(&self) -> Result<i32>

Source

fn depth(&self) -> Result<i32>

Source

fn channels(&self) -> Result<i32>

Source

fn elem_size(&self) -> Result<i32>

Source

fn elem_size1(&self) -> Result<i32>

Source

fn buf_id(&self) -> Result<u32>

get OpenGL opject id

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
