result_in_dart library

Dart implementation of Rust's Result type.

Result<T, E> is the type used for returning and propagating errors. It is a class with the two variants, Ok(T) and Err(E). where T is the type of a successful value and E is the type of an error.

Loosely based on https://doc.rust-lang.org/src/core/result.rs.html source code.
