Module dynamic 

Dynamic configuration.

A configuration producer publishes ConfigSettings over a stream of ConfigUpdates. Two things consume that stream. A caller wanting a live by-key view hands the initial snapshot to ConfigurationLoader::with_dynamic_configuration, then passes each later update to the ConfigUpdater that into_generic returns. The updater keeps a GenericConfiguration current and reports each change through ConfigChangeEvent or a FieldUpdateWatcher. A caller wanting its own representation takes ConfigSetting and ConfigUpdate alone and folds them itself.

Structs

ConfigChangeEvent

Enums

ConfigUpdate
