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?"

โผ
[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

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)
