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

| Order | src/models/order.rs:15 | 6 | Debug, Serialize |
| ... | | | |

### Traits (4)
| Name | Location | Methods | Implementors |
|------|----------|---------|--------------|
| Handler | src/handlers/mod.rs:5 | 3 | AuthHandler, ApiHandler |
| Repository | src/db/mod.rs:12 | 5 | UserRepo, OrderRepo |
| ... | | | |

### Functions (25)

### Single File Analysis

src/handlers/auth.rs

Symbols Hierarchy

mod auth ├── struct AuthHandler │ ├── field: config: Config │ ├── field: db: Pool │ └── impl AuthHandler │ ├── fn new(config, db) -> Self │ ├── fn authenticate(&self, token) -> Result │ └── fn refresh_token(&self, user) -> Result ├── struct Token │ ├── field: value: String │ └── field: expires: DateTime ├── enum AuthError │ ├── InvalidToken │ ├── Expired │ └── Unauthorized └── impl Handler for AuthHandler ├── fn handle(&self, req) -> Response └── fn name(&self) -> &str


## Analysis Features

### 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)

### Dependency Analysis

Internal Dependencies

auth.rs ├── imports from: config.rs, models/user.rs, db/mod.rs └── imported by: main.rs, handlers/mod.rs

user.rs ├── imports from: (none - leaf module) └── imported by: auth.rs, api.rs, tests/


## Symbol Types

| Type | Icon | LSP Kind |
|------|------|----------|
| Module | 📦 | Module |
| Struct | 🏗️ | Struct |
| Enum | 🔢 | Enum |
| Trait | 📜 | Interface |
| Function | ⚡ | Function |
| Method | 🔧 | Method |
| Constant | 🔒 | Constant |
| Field | 📎 | Field |

## Common Queries

| User Says | Analysis |
|-----------|----------|
| "What structs are in this project?" | workspaceSymbol + filter |
| "Show me src/lib.rs structure" | documentSymbol |
| "Find all async functions" | workspaceSymbol + async filter |
| "List public API" | documentSymbol + pub filter |
