Traits§

ExtraResult
Add extra functionalities to the Result type. This trait provides a set of async versions of the standard Result methods. Unlike the standard methods, these methods accept async functions as arguments. It return a Future that resolves to the same result of standard Result counterpart. Unless async functions is needed, it is recommended to use the standard Result methods for performance reason.
