Type Alias QueryResult

pub type QueryResult<T, E = Debug<Error>> = Result<T, E>;

Alias of a Result with an error type of Debug for a diesel::Error.

QueryResult is a Responder when T (the Ok value) is a Responder. By using this alias as a route handler’s return type, the ? operator can be applied to fallible diesel functions in the route handler while still providing a valid Responder return type.

See the module level docs for a usage example.

enum QueryResult<T, E = Debug<Error>> {
    Ok(T),
    Err(E),
}

Variants
