Overview ¶
Package gs_dync provides dynamic configuration binding and refresh capabilities for Go-Spring applications.
It allows application components to register themselves as refreshable objects that automatically update their internal state whenever the underlying configuration changes.
Key components:
- Properties: holds the current configuration and manages all registered `refreshable` objects.
- Value[T]: a type-safe container for dynamic configuration values.
- Listener: allows components to receive change notifications.
- `refreshable`: interface that application components can implement to react to configuration updates.
This package is designed to be thread-safe and suitable for hot-reload scenarios in long-running applications.
