Rust Call Graph
When you need to understand who calls a Rust function or what it calls, this skill uses LSP to build visual call hierarchies. You can trace callers (impact analysis), callees (implementation flow), or both, with configurable depth. It's especially handy when refactoring or trying to understand execution paths in unfamiliar code. The ASCII tree diagrams are clear and the bidirectional view gives you the full picture of a function's role in your codebase. One nice touch: it provides analysis like hot paths and complexity metrics after showing the graph, so you get context beyond just the visualization.

Rust Call Graph
Visualize function call relationships using LSP call hierarchy.
Usage
/rust-call-graph <function_name> [--depth N] [--direction in|out|both]
Options:
--depth N: How many levels to traverse (default: 3)--direction:in(callers),out(callees),both
Examples:
/rust-call-graph process_request- Show both callers and callees/rust-call-graph handle_error --direction in- Show only callers/rust-call-graph main --direction out --depth 5- Deep callee analysis
LSP Operations
1. Prepare Call Hierarchy
Get the call hierarchy item for a function.
LSP(
operation: "prepareCallHierarchy",
filePath: "src/handler.rs",
line: 45,
character: 8
)
2. Incoming Calls (Who calls this?)
LSP(
operation: "incomingCalls",
filePath: "src/handler.rs",
line: 45,
character: 8
)
3. Outgoing Calls (What does this call?)
LSP(
operation: "outgoingCalls",
filePath: "src/handler.rs",
line: 45,
character: 8
)
