)
Use when:
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
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
## 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"
}
}
```
## Traits implemented by `User`
**Struct defined at:** src/models/user.rs:10

## Trait Implementation Coverage
Trait: Handler (3 required methods)
| Implementor | handle() | name() | priority() | Complete |
|-------------|----------|--------|------------|----------|
| AuthHandler | ✅ | ✅ | ✅ | Yes |
| ApiHandler | ✅ | ✅ | ❌ default | Yes |
| MockHandler | ✅ | ✅ | ✅ | Yes |
## Blanket Implementations
The following blanket impls may apply to your types:
| Trait | Blanket Impl | Applies To |
|-------|--------------|------------|
| From<T> | `impl<T> From<T> for T` | All types |
| Into<U> | `impl<T, U> Into<U> for T where U: From<T>` | Types with From |
| ToString | `impl<T: Display> ToString for T` | Types with Display |
| User Says | Action |
|---|---|
| "Who implements X?" | goToImplementation on trait |
| "What traits does Y impl?" | Grep for impl * for Y |
| "Show trait hierarchy" | Find super-traits recursively |
| "Is X: Send + Sync?" | Check std trait impls |
