autoMap PATH can be defined as method comment.

You can use autoMap to automatically match fields from a sub struct to the target struct. This is useful, when you've a struct that is the flattened version of another struct.

autoMap PATH accepts one parameter which is a path to a substruct on the source struct. You can specify nested substructs by separating the fields with .. Example: Nested.SubStruct
