Struct AppsyncResponse 

pub struct AppsyncResponse { /* private fields */ }

Response structure returned to AWS AppSync from a Lambda resolver.

Can contain either successful data or error information, but not both. Should be constructed using From implementations for either Value (success) or AppsyncError (failure).

Examples

// Success response
let response: AppsyncResponse = json!({ "id": 123 }).into();

// Error response
let error = AppsyncError::new("NotFound", "Resource not found");
let response: AppsyncResponse = error.into();

Implementations

impl AppsyncResponse

pub fn unauthorized() -> Self

Returns an unauthorized error response

This creates a standard unauthorized error response for when a request lacks proper authentication.

Examples

let response = AppsyncResponse::unauthorized();

pub fn data(&self) -> Option<&Value>

Returns a reference to the response data, if present

Examples

let response = AppsyncResponse::from(json!({"user": "Alice"}));
assert!(response.data().is_some());

pub fn error(&self) -> Option<&AppsyncError>

Returns a reference to the response error, if present

Examples

let error = AppsyncError::new("NotFound", "User not found");
let response = AppsyncResponse::from(error);
assert!(response.error().is_some());
