type Snapshot ¶

type Snapshot struct {
	// contains filtered or unexported fields
}

Snapshot captures the current state of all registered dynamic values. Useful for debugging and logging current configuration.

func NewSnapshot() *Snapshot

func (s *Snapshot) Capture() map[string]any

func (s *Snapshot) Register(name string, getter func() any)

type Value ¶

type Value[T any] struct {
	// contains filtered or unexported fields
}

Value holds a configuration value that can be swapped atomically at runtime.

This is the fundamental building block for dynamic configuration. Any policy or config struct can be wrapped in a Value for hot-swapping.

Thread-safe: reads use atomic.Value, writes use sync.Mutex.

func NewValue[T any](initial T) *Value[T]

func (v *Value[T]) Get() T

func (v *Value[T]) OnChange(fn func(old, new T))

func (v *Value[T]) Set(newVal T)
