Overview

Custom serializers

You can build your custom encoder, if you like. The value of params_encoder can be any Crest::ParamsEncoder object that responds to: #encode(Hash) #=> String

The encoder will affect both how Crest processes query strings and how it serializes POST bodies.

The default encoder is Crest::FlatParamsEncoder.
