How errors are reported (ErrorHandlerFeature's options); only before initialize() ends.
A registered feature. Built-in names (and names added to FeatureRegistry)
return their feature's type; any other name takes the type as T.
The names of the registered features, in registration order.
The logger features should use (see KernelConfig.logger).
Answers requests by the response contract (see KernelConfig.contract).
Replaces the logger; only before initialize() (WebPlugin passes the App's).
Stops accepting connections, waits for in-flight requests to finish, then shuts features down in reverse dependency order (the auth feature before the db it uses). Every feature is shut down even if one fails; the failures are rethrown together at the end.
Core microkernel orchestrator that manages features, dependencies, and application lifecycle.
