Struct AndroidSurfaceControlHandle 

pub struct AndroidSurfaceControlHandle { /* private fields */ }

Available on Android only.

ASurfaceControl* compositor layer (API 29+).

Implementations

impl AndroidSurfaceControlHandle

pub unsafe fn try_from_raw( surface_control: *mut c_void, keep_alive: Option<KeepAlive>, ) -> Result<Self, InvalidHandleError>

Wrap an ASurfaceControl* compositor layer (API 29+). Borrowing: the handle is stored non-owningly, this type has no Drop, and every obligation below extends to each Clone.

Safety

• surface_control must point to a live ASurfaceControl created by ASurfaceControl_create / ASurfaceControl_createFromWindow and not yet ASurfaceControl_released. Null is rejected as InvalidHandleError::NullPointer and is not a caller obligation.
• Refcount: no ASurfaceControl_acquire is issued and there is no Drop that releases. The caller’s reference must outlive this value and every Clone of it — park it in keep_alive, or hold it directly when that is None.
• Like AndroidNativeWindowHandle, this is an output-side handle: the interop layer submits transactions against it and never imports from it.
• AndroidSurfaceControlHandle is Send + Sync; the caller asserts the layer may be driven from the interop thread. ASurfaceTransaction batching is itself thread-safe, but the caller must not interleave its own transactions on the same layer in a way that reorders the interop layer’s.
