require "./match_data"
module Spectator::Matchers
# Match data that does nothing useful.
# This is a workaround for a compilation issue - hopefully temporary.
# This might be the same issue that `DummyExample` solves.
# Without this, the Crystal compiler complains:
# ```text
# undefined method 'Spectator::Matchers::MatchData#message()'
# ```
# The method is clearly defined by `MatchData`, just abstract.
# Additionally, there are implementations of `MatchData` -
# see `NilMatcher::MatchData`.
private struct DummyMatchData < MatchData
# Dummy values.
def values
{expected: nil, actual: nil}
end
# Dummy message.
def message
"DUMMY"
end
# Dummy message.
def negated_message
"DUMMY"
end
end
