Module: Shipping::HashMethodAccess

Defined in:

app/services/shipping/hash_method_access.rb

Overview

Gives a plain Hash attribute-style read access (response.success?,
response.rates) so shipping adapters can hand callers a response hash
that quacks like an object. extend a response hash with this instead of
defining singleton method_missing on it — YARD can't document
def obj.method_missing ("Undocumentable method defined on object
instance"), and the one-liner keeps every adapter consistent.

response = { success: true, rates: [] }
response.extend(Shipping::HashMethodAccess)
response.success? # => true
