Struct Incoming

pub struct Incoming(/* private fields */);

Implements access to the incoming namespace for a driver. It provides methods for accessing incoming protocols and services by either their marker or proxy types, and can be used as a [Directory] with the functions in [fuchsia_component::client].

Implementations

impl Incoming

pub fn connect_protocol<T: Connect>(&self) -> Result<T, Status>

Connects to the protocol in the service instance’s path in the incoming namespace. Logs and returns a [Status::CONNECTION_REFUSED] if the service instance couldn’t be opened.

pub fn service_marker<M: ServiceMarker>( &self, _marker: M, ) -> ServiceConnector<'_, M::Proxy>

Creates a connector to the given service’s default instance by its marker type. This can be convenient when the compiler can’t deduce the [ServiceProxy] type on its own.

See ServiceConnector for more about what you can do with the connector.

Example

let service = context.incoming.service_marker(fidl_fuchsia_hardware_i2c::ServiceMarker).connect()?;
let device = service.connect_to_device()?;

pub fn service<P>(&self) -> ServiceConnector<'_, P>

Creates a connector to the given service’s default instance by its proxy type. This can be convenient when the compiler can deduce the [ServiceProxy] type on its own.

See ServiceConnector for more about what you can do with the connector.

Example

struct MyProxies {
    i2c_service: fidl_fuchsia_hardware_i2c::ServiceProxy,
}
let proxies = MyProxies {
    i2c_service: context.incoming.service().connect()?;
};
