Struct devices::ChildProcIntf

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

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.

Fields

tube: Tube

pid: pid_t

debug_label: String

Implementations

impl ChildProcIntf

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

Trait Implementations

impl<'de> Deserialize<'de> for ChildProcIntf

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ChildProcIntf

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<ChildProcIntf> for ProxyDevice

type Error = Error

The type returned in the event of a conversion error.

fn try_from(child_proc_intf: ChildProcIntf) -> Result<Self, Error>

Performs the conversion.
