• v2.0.0 Changes

  August 22, 2019

  📦 Optuple package on nuget.org

  What's New

  📄 There is a new type called OptionModule that is designed to be statically imported, like so:

  using static Optuple.OptionModule;
  

  This will make the following common methods available for use without type qualification:

  • Some
  • None<>
  • SomeWhen
  • NoneWhen

  This permits you to, for example, simply write Some(42) and None<int>() instead of Option.Some(42) and None<int>(), respectively.

  💥 Breaking Changes

  The methods below on Option were completely redundant. They were accidentally leaked from an older design and have been removed in this release to avoid confusion.

  public static (bool HasValue, T Value) From<T>((bool, T) option)
public static (bool HasValue, T Value) ToOption<T>(this (bool HasValue, T Value) option)
public static (bool HasValue, T Value) Flagged<T>(this (bool HasValue, T Value) option)

  The removal of these methods is the primary reason for bumping the major version number to 2. Otherwise, all other types and their members remain unchanged.
