GenerateMatch

Generate a .Match method to switch over types with a known set of cases. The idea is to create expression-style switch statements that ensure all conditions are handled.

The supported types are:

  • enums: Match will take function parameters for each case of the enum

  • enumeration classes: The source generator will infer each internal class case

{
    public record Ok(T Value): Result<T, R>;

}

var res = new Result<int, string>.Ok(100);
Assert.Equal("100",
    res.MatchResult => ok.Value.ToString(), error => error.Value.ToString()));
