Struct Router 

Source 
pub struct Router<T: CapabilityBound> { /* private fields */ }
Expand description

A Router is a capability that lets the holder obtain other capabilities asynchronously. Router is the object capability representation of Routable.

During routing, a request usually traverses through the component topology, passing through several routers, ending up at some router that will fulfill the request instead of forwarding it upstream.

Router differs from Router in that it is parameterized on the capability type T. Instead of a Capability, Router returns a RouterResponse. Router will supersede Router.

Implementations§
