module Mocktail::Matchers
# Captors are conceptually complex implementations, but with a simple usage/purpose:
# They are values the user can create and hold onto that will return a matcher
# and then "capture" the value made by the real call, for later analysis & assertion.
#
# Unlike other matchers, these don't make any useful sense for stubbing, but are
# very useful when asserting complication call verifications
#
# The fact the user will need the reference outside the verification call is
# why this is a top-level method on Mocktail, and not included in the |m| block
# arg to stubs/verify
#
# See Mockito, which is the earliest implementation I know of:
# https://javadoc.io/doc/org.mockito/mockito-core/latest/org/mockito/Captor.html
