optionalh

optionalh is a Rust library that provides an implementation of an optional type, often referred to as `Option`. This `Option` type is a generic enum that can represent either the presence of a value or the absence of a value. It is defined as `enum Option<T> { None, Some(T) }`. The `None` variant signifies no value, while the `Some(T)` variant holds a value of type `T`. This pattern is fundamental in Rust for handling situations where a value might be absent, preventing null pointer exceptions and promoting safer code.

The optionalh library aims to offer a robust and idiomatic way to work with optional values. It provides various methods for interacting with `Option` instances, such as checking for presence, unwrapping values, providing default values, and transforming the contained value. These methods allow developers to express intentions clearly and handle potential absence of data gracefully. For example, methods like `map`, `and_then`, and `unwrap_or` are commonly used to manipulate and extract data from `Option` types.

The primary benefit of using optionalh, or Rust's built-in `Option` type, is to make code more explicit about the possibility of missing values. Instead of returning a special value like `null` or `None` which can lead to runtime errors if not checked, Rust's `Option` forces the developer to explicitly handle both the `Some` and `None` cases, either through pattern matching or by utilizing the provided helper methods. This enhances code safety and readability.
