Function GoTransform

codegen/go_transform.go:56–74

GoTransform produces Go code that initializes the data structure defined by target from an instance of the data structure described by source. The data structures can be objects, arrays or maps. The algorithm matches object fields by name and ignores object fields in target that don't have a match i
