Dependency Resolution API

• resolve<T>() — Locates a dependency instance or throws if missing.
• resolveAsync<T>() — Async variant for dependencies requiring async binding.
• tryResolve<T>() — Returns null if no such binding is registered (sync).
• tryResolveAsync<T>() — Returns null async if no such binding is registered.

null from tryResolve/tryResolveAsync means “not registered”, not “failed”: a binding that is registered but is asked for the wrong way still reports the problem. Calling tryResolve<T>() on an async binding throws and points you to resolveAsync<T>(), a parameterized provider invoked without params throws, and errors raised by a provider propagate to the caller.

Supports:

• Synchronous and asynchronous dependencies
• Named dependencies
• Provider functions with and without runtime parameters
