Documentation

This module provides two main types: Option and Result, which are useful for handling optional values and error cases in a functional programming style.

Option

The Option type represents an optional value. It can be either Some containing a value, or None representing the absence of a value.

Result

The Result type represents the outcome of an operation that might fail. It can be either Success containing a value, or ResError containing an error.

Usefulness in Functional Programming and Pipeline-Oriented Programming

These types are particularly valuable in functional programming (FP) and pipeline-oriented programming for several reasons:

1. Explicit Error Handling: Option and Result types make error handling explicit in the type system. This encourages developers to consider and handle edge cases, leading to more robust code.

2. Composition: These types can be easily composed and chained in functional pipelines. For example, you can chain multiple operations that return Option or Result types, handling success and failure cases elegantly.

3. Avoiding Null/Undefined: By using Option, you can avoid null or undefined values, which are common sources of runtime errors. This leads to safer, more predictable code.

4. Separation of Concerns: Result type separates the success path from the error path, allowing you to process them independently. This separation often leads to cleaner, more maintainable code.

5. Declarative Style: These types promote a more declarative programming style, where you describe what you want to happen in different scenarios (Some/None, Success/Error) rather than imperatively handling each case.

6. Improved Readability: By using these types, the intent of the code becomes clearer. It's immediately obvious when a function might not return a value or might fail.

7. Pattern Matching: These types work well with pattern matching, a powerful feature in many functional programming languages, allowing for concise and expressive code.

By leveraging Option and Result types, you can create more robust, composable, and expressive code, aligning well with the principles of functional and pipeline-oriented programming.
