Constructor Details

#initialize(attrs, scope) ⇒ AttributesIterator

attrs and scope are static per validator; only params varies per request, so an instance can be built once and reused (it keeps no request-derived state). Reused instances are shared across threads, so each must stay free of mutable instance state.
