🎯 Option<T> Functional Cheat Sheet

🧩 Option Overview

Represents a value that might exist (Some) or not (None), avoiding nulls and enabling functional composition.

Option<int> maybeNumber = Option.Some(42);
Option<string> emptyName = Option.None<string>();

🏗 Construction

Syntax	Description
`Option.Some(value)`	Wraps a non-null value as `Some`
`Option.None<T>()`	Creates a `None` of type `T`
`value.ToOption()`	Converts value or default to Option
`value.ToOption(predicate)`	Converts only if predicate returns true
`nullable.ToOption()`	Converts nullable struct to Option

🧪 Pattern Matching

option.Match(
    some => $"Value: {some}",
    ()   => "No value"
);

Or via deconstruction:

var (isSome, value) = option;

Or with TryGet:

if (option.TryGetValue(out var value)) { /* use value */ }

🔧 Transformation

Method	Description
`Map(func)`	Transforms value inside Some
`Bind(func)`	Chains function that returns another Option
`ToResult(errorFn)`	Converts Option to `Result<T, TError>`
`ToNullable()`	Converts to nullable (structs only)
`ToEnumerable()`	Converts to `IEnumerable<T>`

🪄 LINQ Support

var result =
    from name in Option.Some("Jason")
    from greeting in Option.Some($"Hello, {name}")
    select greeting;

Via Select, SelectMany, or SelectAwait (async LINQ)

🔁 Async Support

Method	Description
`MapAsync(func)`	Awaits and maps value
`BindAsync(func)`	Awaits and chains async Option-returning func
`MatchAsync(onSome, onNone)`	Async pattern match
`SelectAwait(func)`	LINQ-friendly async projection

🧯 Fallbacks and Conversions

option.OrElse("fallback");      // returns value or fallback
option.OrThrow();               // throws if None
option.IsSome();                // true if Some
option.IsNone();                // true if None

🐛 Debugging & Output

option.ToString(); // Outputs "Some(value)" or "None"
