Module: Boldsign::CaseConvert

Defined in:
lib/boldsign/case_convert.rb

Overview

Converts arbitrary Ruby hash keys (snake_case, camelCase, or PascalCase; Symbol or String) to camelCase string keys recursively, matching the casing the BoldSign REST API expects in request bodies. Non-Hash and non-Array values — including binary IO objects, FilePart instances, scalars, dates, etc. — pass through untouched.
