Struct SurfacePump 

pub struct SurfacePump<T: Send + 'static> { /* private fields */ }

Owning handle for the pump. On Windows, dropping it shuts the thread down (bounded join, then detach - a thread wedged in a driver call is left behind rather than hanging the GUI thread).

Implementations

impl<T: Send + 'static> SurfacePump<T>

pub unsafe fn spawn( window: &Window<'_>, device_lost: &Arc<AtomicBool>, init: PumpInitFn<T>, ) -> Option<Self>

Build the pump for a baseview window. On Windows this spawns the pump thread and returns immediately (GPU init runs there; poll Self::take_init); elsewhere init runs synchronously and take_init succeeds on the first call.

device_lost is raised if the pump thread panics so the editor’s device-loss recovery can rebuild with a fresh pump.

Safety

The window must remain valid while the pump lives - the editor guarantees this by dropping the pump before closing its child window (a destroyed HWND fails surface creation with a driver error, not UB).

pub fn take_init(&mut self) -> Option<T>

Poll for the init closure’s product (non-blocking). Returns it exactly once.

pub fn client(&self) -> PumpClient
