maidsafe_utilities::unwrap_result!

macro_rules! unwrap_result {
    ($result:expr) => { ... };
}

A replacement for calling unwrap() on a Result.

This macro is intended to be used in all cases where we unwrap a Result to deliberately panic in case of error, e.g. in test-cases. Such unwraps don't give a precise point of failure in our code and instead indicate some line number in the Rust core library. This macro provides a precise point of failure and decorates the failure for easy viewing.

Examples

let some_result: Result<String, std::io::Error> = Ok("Hello".to_string());
let string_length = unwrap_result!(some_result).len();
assert_eq!(string_length, 5);
