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
- 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.
- 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
