Trait Implementations

impl<'a> Capturer for SharedCapturer<'a>

fn dxgi_output_desc(&self) -> Result<DXGI_OUTPUT_DESC>

This is usually used to get the screen’s position and size.

fn dxgi_outdupl_desc(&self) -> DXGI_OUTDUPL_DESC

This is usually used to get the screen’s pixel width/height and buffer size.

fn buffer(&self) -> &[u8]

Get the buffer of the last captured frame. The buffer is in BGRA32 format.

fn buffer_mut(&mut self) -> &mut [u8]

Get the buffer of the last captured frame. The buffer is in BGRA32 format.

fn check_buffer(&self) -> Result<()>

Check buffer size.

fn pointer_shape_buffer(&self) -> &[u8]

Get the buffer of the captured pointer shape.

fn pointer_shape_updated(&self) -> bool

Return true if the pointer shape is updated.

fn capture(&mut self) -> Result<DXGI_OUTDUPL_FRAME_INFO>

Capture the screen and return the frame info. The pixel data is stored in the buffer.

fn safe_capture(&mut self) -> Result<DXGI_OUTDUPL_FRAME_INFO>

Check buffer size before capture. The pixel data is stored in the buffer.

fn capture_with_pointer_shape( &mut self ) -> Result<(DXGI_OUTDUPL_FRAME_INFO, Option<DXGI_OUTDUPL_POINTER_SHAPE_INFO>)>

Capture the screen and return the frame info. The pixel data is stored in the buffer. If mouse is updated, the Option<DXGI_OUTDUPL_POINTER_SHAPE_INFO> is Some. The pointer shape is stored in the pointer_shape_buffer.

fn safe_capture_with_pointer_shape( &mut self ) -> Result<(DXGI_OUTDUPL_FRAME_INFO, Option<DXGI_OUTDUPL_POINTER_SHAPE_INFO>)>

Check buffer size before capture. The pixel data is stored in the buffer. If mouse is updated, the Option<DXGI_OUTDUPL_POINTER_SHAPE_INFO> is Some. The pointer shape is stored in the pointer_shape_buffer.

impl<'a> Drop for SharedCapturer<'a>

fn drop(&mut self)

Executes the destructor for this type.
