Rust Trait Explorer

Discover trait implementations and understand polymorphic designs.

Usage

/rust-trait-explorer <TraitName|StructName>

Examples:

• /rust-trait-explorer Handler - Find all implementors of Handler trait
• /rust-trait-explorer MyStruct - Find all traits implemented by MyStruct

LSP Operations

Go to Implementation

Find all implementations of a trait.

LSP(
  operation: "goToImplementation",
  filePath: "src/traits.rs",
  line: 10,
  character: 11
)

Use when:

• Trait name is known
• Want to find all implementors
• Understanding polymorphic code

Workflow

Find Trait Implementors

User: "Who implements the Handler trait?"
    │
    ▼
[1] Find trait definition
    LSP(goToDefinition) or workspaceSymbol
    │
    ▼
[2] Get implementations
    LSP(goToImplementation)
    │
    ▼
[3] For each impl, get details
    LSP(documentSymbol) for methods
    │
    ▼
[4] Generate implementation map

Find Traits for a Type

User: "What traits does MyStruct implement?"
    │
    ▼
[1] Find struct definition
    │
    ▼
[2] Search for "impl * for MyStruct"
    Grep pattern matching
    │
    ▼
[3] Get trait details for each
    │
    ▼
[4] Generate trait list

Output Format

Trait Implementors

## Implementations of `Handler`

**Trait defined at:** src/traits.rs:15

​```rust
pub trait Handler {
    fn handle(&self, request: Request) -> Response;
    fn name(&self) -> &str;
}
​```

### Implementors (4)

| Type | Location | Notes |
|------|----------|-------|
| AuthHandler | src/handlers/auth.rs:20 | Handles authentication |
| ApiHandler | src/handlers/api.rs:15 | REST API endpoints |
| WebSocketHandler | src/handlers/ws.rs:10 | WebSocket connections |
| MockHandler | tests/mocks.rs:5 | Test mock |

### Implementation Details

#### AuthHandler
​```rust
impl Handler for AuthHandler {
    fn handle(&self, request: Request) -> Response {
        // Authentication logic
    }

    fn name(&self) -> &str {
        "auth"
    }
}
​```

#### ApiHandler
​```rust
impl Handler for ApiHandler {
    fn handle(&self, request: Request) -> Response {
        // API routing logic
    }

    fn name(&self) -> &str {
        "api"
    }
}
​```
