Struct ShutdownIc

pub struct ShutdownIc { /* private fields */ }

A shutdown IC device.

Implementations

impl ShutdownIc

pub fn new(recv: Receiver<ShutdownRpc>) -> Self

Returns a new shutdown IC, using recv to receive shutdown requests.

Trait Implementations

impl InspectMut for ShutdownIc

fn inspect_mut(&mut self, req: Request<'_>)

Inspects the object.

impl SaveRestoreSimpleVmbusDevice for ShutdownIc

fn save_open(&mut self, runner: &Self::Runner) -> SavedState

Saves the channel.

fn restore_open( &mut self, saved_state: Self::SavedState, channel: RawAsyncChannel<GpadlRingMem>, ) -> Result<Self::Runner, ChannelOpenError>

Restores the channel.

impl SimpleVmbusDevice for ShutdownIc

type SavedState = SavedState

The saved state type.

type Runner = ShutdownChannel

The type used to run an open channel.

fn offer(&self) -> OfferParams

The channel offer parameters.

fn inspect(&mut self, req: Request<'_>, runner: Option<&mut Self::Runner>)

Inspects a channel.

fn open( &mut self, channel: RawAsyncChannel<GpadlRingMem>, _guest_memory: GuestMemory, ) -> Result<Self::Runner, ChannelOpenError>

Opens the channel, returning the runner to use to run the channel.

fn run<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 mut self, stop: &'life1 mut StopTask<'life2>, runner: &'life3 mut Self::Runner, ) -> Pin<Box<dyn Future<Output = Result<(), Cancelled>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Runs an open channel until stop is signaled.

fn supports_save_restore( &mut self, ) -> Option<&mut dyn SaveRestoreSimpleVmbusDevice<SavedState = Self::SavedState, Runner = Self::Runner>>

Returns a trait used to save/restore the device.

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Closes the channel after the runner has been dropped.
