Struct devices::proxy::ChildProcIntf

source ·

pub struct ChildProcIntf {
    tube: Tube,
    pid: pid_t,
    debug_label: String,
}

Expand description

ChildProcIntf is the interface to the device child process.

ChildProcIntf implements Serialize, and can be sent across process before it functions as a ProxyDevice. However, a child process shall only correspond to one ProxyDevice. The uniqueness is checked when ChildProcIntf is casted into ProxyDevice.

Implementations§

source §

impl ChildProcIntf

source

pub fn new<D: BusDevice, P: PrepareFork>( device: D, jail: Minijail, keep_rds: Vec<RawDescriptor>, swap_prepare_fork: &mut Option, ) -> Result<ChildProcIntf, Error>

Creates ChildProcIntf that shall be turned into exactly one ProxyDevice.

The ChildProcIntf struct holds the interface to the device process. It shall be turned into a ProxyDevice exactly once (at an arbitrary process). Since ChildProcIntf may be duplicated by serde, the uniqueness of the interface is checked when ChildProcIntf is converted into ProxyDevice.

§Arguments

device - The device to isolate to another process.
jail - The jail to use for isolating the given device.
keep_rds - File descriptors that will be kept open in the child.

impl<T> Downcast for T
where T: Any,

§

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

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>) -> Rc<dyn Any>

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.

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

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