PrepareCallHierarchy.rs

1//! `PrepareCallHierarchy` gRPC RPC handler.
2//!
3//! The entry-point call for VS Code's call hierarchy feature. Mountain calls
4//! this with `uri + position`; Cocoon's `$prepareCallHierarchyItems` dispatch
5//! asks the registered provider to return the root `CallHierarchyItem` at that
6//! location. Without this step the incoming/outgoing calls panels are always
7//! empty even when the provider is correctly registered.
