fuchsia-component is a crate designed to allow components to launch, connect to, and provide services to other components.
Some of the functionality provided by fuchsia-component was formerly present in the fuchsia-app crate, which is now deprecated.
fuchsia-component can do everything fuchsia-app could, but includes a new name, a more ergonomic API, and a more flexible directory implementation that allows more precisely managing where outgoing services are located within the outgoing directory hierarchy. fuchsia-app exposed all services at /* and /public/*, while fuchsia-component allows developers to choose a precise location for each service. This is critical for developers who wish to expose internal-only debugging services such as the Inspect API.
