pub struct CommitStatusProviderSynchronousProxy { /* private fields */ }

Implementations

impl CommitStatusProviderSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<CommitStatusProviderEvent, 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 is_current_system_committed( &self, ___deadline: MonotonicInstant, ) -> Result<EventPair, Error>

Determines whether the currently booted system is committed, and immediately returns an EventPair.

• If the currently booted system is committed, the ZX_USER_SIGNAL_0 signal is asserted on the EventPair, e.g. the signal is asserted before the EventPair is returned.
• If the commit is pending, no signals are asserted on the EventPair. When the system is committed, ZX_USER_SIGNAL_0 is asserted on the EventPair.
• If the system fails to commit the currently booted version, the system will reboot and terminate the component serving [CommitStatusProvider], which will assert ZX_EVENTPAIR_PEER_CLOSED. At this point, any remaining EventPairs will observe the ZX_EVENTPAIR_PEER_CLOSED signal.

• response event an EventPair with rights ZX_RIGHTS_BASIC.
