Rust Symbol Analyzer

This parses LSP symbols from your Rust codebase to give you a structural overview of what's where. It'll show you all structs, traits, functions, and enums across the project or drill into a single file with hierarchy. Useful when you're dropped into an unfamiliar codebase or need to audit what's public before a release. The output includes tables with locations, visibility, and relationship info. It can filter by symbol type and attempts complexity metrics based on function count and lines. Honestly most valuable for that initial "what am I looking at" moment rather than ongoing development, since your IDE already does symbol search, but the cross-file categorization view is handy for documentation or onboarding.

Files

Rust Symbol Analyzer

Analyze project structure by examining symbols across your Rust codebase.

Usage

/rust-symbol-analyzer [file.rs] [--type struct|trait|fn|mod]

Examples:

/rust-symbol-analyzer - Analyze entire project
/rust-symbol-analyzer src/lib.rs - Analyze single file
/rust-symbol-analyzer --type trait - List all traits in project

LSP Operations

1. Document Symbols (Single File)

Get all symbols in a file with their hierarchy.

LSP(
  operation: "documentSymbol",
  filePath: "src/lib.rs",
  line: 1,
  character: 1
)

Returns: Nested structure of modules, structs, functions, etc.

2. Workspace Symbols (Entire Project)

Search for symbols across the workspace.

LSP(
  operation: "workspaceSymbol",
  filePath: "src/lib.rs",
  line: 1,
  character: 1
)

Note: Query is implicit in the operation context.

Workflow

User: "What's the structure of this project?"
    │
    ▼
[1] Find all Rust files
    Glob("**/*.rs")
    │
    ▼
[2] Get symbols from each key file
    LSP(documentSymbol) for lib.rs, main.rs
    │
    ▼
[3] Categorize by type
    │
    ▼
[4] Generate structure visualization
