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

Complexity Metrics

## Complexity Analysis

| File | Structs | Functions | Lines | Complexity |

|------|---------|-----------|-------|------------|

| src/handlers/auth.rs | 2 | 8 | 150 | Medium |

| src/models/user.rs | 3 | 12 | 200 | High |

| src/config.rs | 1 | 3 | 50 | Low |

**Hotspots:** Files with high complexity that may need refactoring

- src/handlers/api.rs (15 functions, 300 lines)
