Static mappers and extension methods

Mapperly supports static mappers and extension methods:

[Mapper]
public static partial class CarMapper
{
    public static partial CarDto CarToCarDto(this Car car);

    private static int TimeSpanToHours(TimeSpan t) => t.Hours;
}

Static methods in instantiable class​

Static methods are supported in non-static mapper classes. This supports the static interface use case. When a static mapping method is present, to simplify mapping method resolution and reduce confusion about which mapping method Mapperly uses, all methods must be static.

public interface ICarMapper
{
    static abstract CarDto ToDto(Car car);
}

[Mapper]
public partial class CarMapper : ICarMapper
{
    public static partial CarDto ToDto(Car car);
}
