public record ResultBase
{
public sealed partial record Warning : ResultBase;
}
[DiscriminatedUnion]
public abstract partial record Result : ResultBase
{
public sealed partial record Ok : Result;
public sealed partial record Error : Result;
}
public static class ResultTest
{
public static void ResultFn(Result result)
{
_ = result.Match(ok: _ => 0, warning: _ => 1, error: _ => 2);
}
}
