-- Tests whether the specified event pattern matches the provided event.

-- Most services in Amazon Web Services treat : or \/ as the same character
-- in Amazon Resource Names (ARNs). However, EventBridge uses an exact
-- match in event patterns and rules. Be sure to use the correct ARN
-- characters when creating event patterns so that they match the ARN
-- syntax in the event you want to match.
