PrepareCallHierarchy.rs

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