module com.github.sviperll.result4j

The module provides the definition of the Result-type similar to Result-type in Rust that allows to return either successful result or otherwise some kind of error.

In Java, the native way of reporting errors are exceptions, either checked or unchecked. You do not need Result-type most of the time in Java-code, where you can directly throw exceptions. But there are situations, where more functional-style is used. In such situations pure-functions are expected that throw no exceptions. Handling exception in such situations can be cumbersome and require a lot of boilerplate code. Result-type and associated helper-classes help with exception handling and allow to write idiomatic functional code that can interact with methods that throw exceptions.
