Class: Foobara::BuiltinTypes::Datetime::Casters::Hash

Inherits:
TypeDeclarations::Caster show all
Defined in:
foobara-0.0.110/projects/builtin_types/src/datetime/casters/hash.rb

Overview

TODO: there seems to be an issue with the design here. We cast first and casters are transformers (don’t return errors.) However, it would probably give a better error if we could indicate exactly what was wrong with this hash instead of a catch-all error mixed with all the other casters errors. The obvious solution is to inherit Value::Processor instead. Maybe that would just work without any other changes needed. TODO: try that
