Struct SystemStateTransitionSynchronousProxy

pub struct SystemStateTransitionSynchronousProxy { /* private fields */ }

Implementations

impl SystemStateTransitionSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<SystemStateTransitionEvent, 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 get_termination_system_state( &self, ___deadline: MonotonicInstant, ) -> Result<SystemPowerState, Error>

Gets the termination state.

pub fn get_mexec_zbis( &self, ___deadline: MonotonicInstant, ) -> Result<SystemStateTransitionGetMexecZbisResult, Error>

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.
