pub struct Surface<T: 'static> { /* private fields */ }
Expand description
A GBM rendering surface
Implementations
Return whether or not a surface has free (non-locked) buffers
Before starting a new frame, the surface must have a buffer available for rendering. Initially, a GBM surface will have a free buffer, but after one or more buffers have been locked, the application must check for a free buffer before rendering.
Lock the surface’s current front buffer
Locks rendering to the surface’s current front buffer and returns
a handle to the underlying BufferObject
.
If an error occurs a FrontBufferError
is returned.
Safety
This function must be called exactly once after calling
eglSwapBuffers
. Calling it before any eglSwapBuffers
has happened
on the surface or two or more times after eglSwapBuffers
is an
error and may cause undefined behavior.
Trait Implementations
Receive a raw pointer representing this type.
