PROTOCOLS
Binder
Defined in fuchsia.component/binder.fidl
A framework-provided protocol that allows components that use it to bind to the component that exposes it. The act of connecting to this protocol will trigger the bind. Thus, this protocol contains no methods. For more details on binding, see https://fuchsia.dev/fuchsia-src/concepts/components/v2/lifecycle#binding.
When a component connects to protocol, the component exposing this capability will be started if it's not already running. Upon a failure to start, the component framework will close the server end of the channel with a zx.status epitaph.
Note: The component doesn't need to serve this protocol, it is implemented by the framework.
