# Struct SurfaceState

        gl: Option<GLContext>,
        render: Option<MpvRenderContext>,
        mpv: *mut mpv_handle,

Expand description

Everything the draw handler needs, shared with the GTK callbacks.

## Fields§

§ `gl: Option<GLContext>` § `render: Option<MpvRenderContext>` § `mpv: *mut mpv_handle` § `frame_ready: Arc<AtomicBool>`

Set by mpv’s update callback (on an mpv thread), cleared by the frame clock (on the main thread). The whole cross-thread contract.

§ `callback_ctx: *mut Arc<AtomicBool>`

The boxed clone of `frame_ready` handed to mpv, reclaimed on teardown. Null when no callback is registered.

§ `logged_first_draw: bool` § `logged_first_frame: bool` § `logged_size: (i32, i32)`

Last size we logged, so a size change re-reports rather than staying silent.

§ `logged_no_gl: bool` § `logged_no_window: bool` § `logged_no_size: bool` § `logged_render_fail: bool`

## Implementations§

Source §

### impl SurfaceState

Source

#### fn teardown(&mut self)

Tear down in the order DR-232 requires, with the GL context current.

The update callback is unregistered before the context is freed (inside `destroy`), and the GL objects go while their context is still bound. Getting this wrong is DR-184 on Android restated — a surface outliving its player — and is the likeliest cause of the one unexplained SIGSEGV the spike recorded.
