Struct gbm::Surface

pub struct Surface<'a, T: 'static> { /* fields omitted */ }

A gbm rendering surface

Methods

impl<'a, T: 'static> Surface<'a, T>

fn has_free_buffers(&self) -> bool

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.

fn lock_front_buffer(
    &'a self
) -> Result<SurfaceBufferHandle<'a, T>, FrontBufferError>

Lock the surface's current front buffer

Locks rendering to the surface's current front buffer and returns a handle to the underlying BufferObject

This function must be called exactly once after calling eglSwapBuffers. Calling it before any eglSwapBuffer has happened on the surface or two or more times after eglSwapBuffers is an error.

If an error occurs a FrontBufferError is returned.
