Module: AnyCable::Serializer

Defined in:
lib/anycable/serializer.rb

Overview

Serializer is responsible for converting Ruby objects to and from a transferrable format (e.g., for identifiers, connection/channel state, etc.). It relies on configurable ‘.object_serializer` to handle non-primitive values and handles Hash/Array seririlzation.
