Module LanguageFeatureProvider 

LanguageFeatureProvider (Environment)

Provides language feature intelligence through extension-hosted LSP providers. Manages provider registration, lookup, and invocation for hover, completion, definition, references, formatting, code actions, and more.

Implementation Strategy

The trait implementation is split across multiple helper modules:

• Registration: RegisterProvider, UnregisterProvider
• ProviderLookup: GetMatchingProvider (private helper)
• FeatureMethods: All LSP feature methods (Hover, Completion, etc.)

The single impl LanguageFeatureProviderRegistry for MountainEnvironment block in this file delegates to those helper functions. This satisfies Rust’s orphan rules while keeping code organized and atomic.
