Expand description

Utility for multiplexing a balloon tube between multiple control tubes. Commands are sent and processed serially.

Fields§

Implementations§

source §

impl BalloonTube

source

pub fn new(tube: Tube) -> Self

source

pub fn send_cmd( &mut self, cmd: BalloonControlCommand, key: Option<usize> ) -> Option<(VmResponse, usize)>

Sends or queues the given command to this tube. Associates the response with the given key.

source

pub fn recv(&mut self) -> Result<Vec<(VmResponse, usize)>>

Receives responses from the balloon tube, and returns them with their assoicated keys.

§

impl<T> Downcast for Twhere T: Any,

§

fn into_any(self: Box<T, Global>) -> Box<dyn Any, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T, Global>) -> Rc<dyn Any, Global>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

§

impl<T> DowncastSync for Twhere T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T, Global>) -> Arc<dyn Any + Sync + Send, Global>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
