SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Visualize Rust function call relationships using LSP to help developers understand how functions interact.

Core Features & Use Cases

  • Visualize incoming call relationships (callers) and outgoing call relationships (callees) using LSP
  • Depth-limited traversal to explore call graphs up to N levels
  • Directional views: in, out, or both, with ASCII-style visualization

Quick Start

Run /rust-call-graph <function_name> --depth 3 --direction both to visualize its call graph.

Frequently Asked Questions about rust-call-graph

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I visualize a Rust call graph to understand function interactions?▼

You can visualize a Rust call graph by running the /rust-call-graph command on a function name, which uses LSP to trace and display incoming and outgoing function relationships in an ASCII-style view.

What is the best way to trace callers and callees across deep Rust call chains?▼

Tracing callers and callees across deep Rust call chains is best handled by using the depth option to limit traversal to N levels, allowing you to explore incoming and outgoing calls without overwhelming the visualization.

Does this Rust call graph visualization work with LSP operations?▼

Yes, the Rust call graph visualization works directly with LSP operations, specifically leveraging prepareCallHierarchy, incomingCalls, and outgoingCalls to gather and map the function interaction data.

How do I limit the depth of a Rust call graph visualization?▼

You can limit the depth of a Rust call graph visualization by passing the --depth flag with a number, such as --depth 3, to restrict the traversal of incoming and outgoing calls to that many levels.

Can I view only incoming or outgoing calls separately in a Rust call graph?▼

Yes, you can view calls separately by using the --direction option with in, out, or both, allowing you to focus on either callers or callees exclusively within the visualization.
