ProviderRegistry

interface ProviderRegistry : Registry(source)

Represents a type-safe associative array that stores associations like Key<T> -> Provider<T>.

Provider registries extend Registry by allowing values to be computed lazily through providers. This enables deferred computation, caching, and other advanced value provision strategies.
