Summary
Maps out who calls what in your Rust codebase using LSP call hierarchy. You give it a function name and get an ASCII tree showing callers above, callees below, or both. Supports depth control and direction flags for focused analysis. The bidirectional view is genuinely helpful when you're trying to understand impact radius before refactoring something. Works entirely through LSP operations so it's as accurate as your language server. The mermaid export option is a nice touch for documentation. Basically answers "where is this used" and "what does this depend on" without grepping through files or holding mental state.
