pub struct ViewRefInstalledSynchronousProxy { /* private fields */ }

Implementations

impl ViewRefInstalledSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<ViewRefInstalledEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn watch( &self, view_ref: ViewRef, ___deadline: MonotonicInstant, ) -> Result<ViewRefInstalledWatchResult, Error>

Sets up a callback to fire when the requested |view_ref| is installed.

• If |view_ref| has not already been installed, the |Watch| response will fire when it is.
• If |view_ref| has already been installed, the |Watch| response will fire immediately.
• If |view_ref| is invalid, or becomes invalid (perhaps because the view was destroyed), the |Watch| call returns with an error. The error is not guaranteed to be immediate, but a ViewRef holder can itself determine ViewRef validity by listening for ZX_EVENTPAIR_PEER_CLOSED.

Flow control: The caller is allowed multiple |Watch| calls on multiple ViewRefs. There is at most one response per call back to the client.

Note: Prior to installation, this |Watch| call is kept alive as long as the ViewRef is valid.
