rmc-signature-search

What problem does it solve?

It helps you inventory and locate Rust functions that match a specific API “shape” (async-ness, parameter patterns, return types, and self-kind) across a crate, without manually grepping source code.

Core Features & Use Cases

• Single-function signature lookup: Inspect a specific function’s recorded FunctionSignature fields like is_async, self_param, parameter list, return type, and generics.
• Crate-wide filtered enumeration: List matching functions using filters such as minimum parameter count, parameter type substrings, return type substrings, async-only/sync-only selection, and self-kind classification.
• Pagination and lightweight summaries: Use limit/offset to page through large workspaces, and summary=true to reduce token usage when enumerating many matches.

Quick Start

First build the workspace hypergraph, then query crate-wide matches like “all async functions returning Result that take &Path” and review the ranked per-match results.
