Feature rule

Overrides the default_value of a GrowthBook.Feature. Has a number of optional properties

• condition (GrowthBook.Condition.t/0) - Optional targeting condition
• parent_conditions (list of GrowthBook.ParentCondition.t/0) - Each item defines a prerequisite where a condition must evaluate against a parent feature's value (identified by id). If gate is true, then this is a blocking feature-level prerequisite; otherwise it applies to the current rule only.
• coverage (float/0) - What percent of users should be included in the experiment (between 0 and 1, inclusive)
• force (term/0) - Immediately force a specific value (ignore every other option besides condition and coverage)
• variations (list of term/0) - Run an experiment (A/B test) and randomly choose between these variations
• key (String.t/0) - The globally unique tracking key for the experiment (default to the feature key)
• weights (list of float/0) - How to weight traffic between variations. Must add to 1.
• namespace (GrowthBook.namespace/0) - Adds the experiment to a namespace
• hash_attribute (String.t/0) - What user attribute should be used to assign variations (defaults to id)
• hash_version (integer/0) - The hash version to use (default to 1)
• range (GrowthBook.BucketRange.t/0) - A more precise version of coverage
• ranges (list of GrowthBook.BucketRange.t/0) - Ranges for experiment variations
• meta (list of GrowthBook.VariationMeta.t/0) - Meta info about the experiment variations
• filters (list of GrowthBook.Filter.t/0) - Array of filters to apply to the rule
• seed (String.t/0) - Seed to use for hashing
• name (String.t/0) - Human-readable name for the experiment
• phase (String.t/0) - The phase id of the experiment
• fallback_attribute (String.t/0) - When using sticky bucketing, can be used as a fallback to assign variations
• disable_sticky_bucketing (boolean/0) - If true, sticky bucketing will be disabled for this experiment. (Note: sticky bucketing is only available if a StickyBucketingService is provided in the Context)
• bucket_version (integer/0) - An sticky bucket version number that can be used to force a re-bucketing of users (default to 0)
• min_bucket_version (integer/0) - Any users with a sticky bucket version less than this will be excluded from the experiment
