How to properly handle RMG089 and RMG090

[GiottoVerducci]

I have two records

public record Foo(string ServerId, int Size);
public record Zoo(string? ServerId, int Size);

When mapping Zoo to Foo, I have a message "RMG089 Mapping the nullable source property ServerId of A.Zoo to the target property ServerId of A.Foo which is not nullable"

public static partial Foo Map(Zoo zoo);

The generated code is :

    public static partial class MyMapper
    {
        [global::System.CodeDom.Compiler.GeneratedCode("Riok.Mapperly", "4.3.0.0")]
        public static partial global::A.Foo Map(global::A.Zoo zoo)
        {
            var target = new global::A.Foo(
                zoo.ServerId ?? throw new global::System.ArgumentNullException(nameof(zoo.ServerId)),
                zoo.Size
            );
            return target;
        }
    }

which is totally fine for me.

How can I get rid off the RMG089 message (as well as RMG090) when I'm fine with the code generated?

I see that a new attribute SuppressNullMismatchDiagnostic has been added to prerelease version, but I can only be put on the MapProperty attribute, and I don't want to add that attribute for each property (this sample is kept simple for illustration, but I have many more nullable properties) but globally (or at least at the class level).

You can do this globally or on each method with attributes or an editorconfig file, see docs.
