🚀 Functional.Toolkit.OptionType

Functional.Toolkit.OptionType is a lightweight library that provides an implementation of the Option type in C#. The Option type is a functional programming concept that represents a value that may or may not be present. This can help reduce the number of null checks in your code, making it more robust and easier to reason about.

Here its just a few examples, check all the available extensions in the OptionExtensions.cs file

Usage

//Object Initialization

var option1 = Option.From((ClassForTest)null); //will automatically determine if its None or Some based on the generic type
var option2 = Option.From(new ClassForTest());
var option3 = Option.None<ClassForTest>();
var option4 = Option.Some(new ClassForTest());
...

//Sync
var maybeClass = await MaybeGetClass();

maybeClass
    .WhenSome(value =>
    {
        Console.WriteLine($"Proceed doing something with the value: {value.Name}");
        //It could be whatever you want, here you have the value of the type of the Option
        //Example:
        //Call another methods, write in the DB, Publish to a Service Bus, infinity...
    })
    .WhenNone(() =>
    {
        Console.WriteLine("Proceed as a fallback without the value");
        //since the Option is None the value couldn't be found.
        //Example:
        //Write logs, alerts, whatever.
    })
    .WhenAny(maybeValue =>
    {
        Console.WriteLine("Despite having a value or not this will be execute and you can decide what to do.");
        Console.WriteLine($"Does my object has a value? {maybeValue.HasValue}");
    });


//Async
var maybeClassTask = MaybeGetClass();

var result = await maybeClassTask
    .WhenSomeAsync(value => 
    { 
        Console.WriteLine($"Proceed doing something with the value: {value.Name}");
        return Task.CompletedTask;
    })
    .WhenNoneAsync(() =>
    {
        Console.WriteLine("Proceed as a fallback without the value");
        return Task.CompletedTask;
    }).WhenAnyAsync(maybeValue =>
    {
        Console.WriteLine($"Does my object has a value? {maybeValue.HasValue}");
    });
