// Use this operation to define a segment of your audience. A segment is a portion
// of your audience that share one or more characteristics. Examples could be
// Chrome browser users, users in Europe, or Firefox browser users in Europe who
// also fit other criteria that your application collects, such as age. Using a
// segment in an experiment limits that experiment to evaluate only the users who
// match the segment criteria. Using one or more segments in a launch allows you to
// define different traffic splits for the different audience segments. For more
// information about segment pattern syntax, see Segment rule pattern syntax (https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Evidently-segments.html#CloudWatch-Evidently-segments-syntax.html)
// . The pattern that you define for a segment is matched against the value of
// evaluationContext , which is passed into Evidently in the EvaluateFeature (https://docs.aws.amazon.com/cloudwatchevidently/latest/APIReference/API_EvaluateFeature.html)
// operation, when Evidently assigns a feature variation to a user.
