Struct SystemStateTransitionProxy

pub struct SystemStateTransitionProxy { /* private fields */ }

Implementations§

impl SystemStateTransitionProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.system.state/SystemStateTransition.

pub fn take_event_stream(&self) -> SystemStateTransitionEventStream

Get a Stream of events from the remote end of the protocol.

§Panics

Panics if the event stream was already taken.

pub fn get_termination_system_state( &self, ) -> QueryResponseFut<SystemPowerState, DefaultFuchsiaResourceDialect>

Gets the termination state.

pub fn get_mexec_zbis( &self, ) -> QueryResponseFut<SystemStateTransitionGetMexecZbisResult, DefaultFuchsiaResourceDialect>

When the system termination state is MEXEC, in the course of shutting down, driver_manager will perform an mexec itself after suspending all drivers. This method allows driver manager to fetch the kernel and data ZBIs to be passed to zx_system_mexec().

This method only should only be invoked in the case MEXEC shutdown.

It is expected that the ZBI items specified by zx_system_mexec_payload_get() have not yet been appended to the provided data ZBI.

Returns

ZX_ERR_BAD_STATE: The termination system state is not set to MEXEC.
