List,
Single(Box<dyn Calculable + 'static>),

}

Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Single(Box<dyn Calculable + 'static>)
Obtain the value of a single feature.
Simple(Box<dyn Calculable + 'static>)
Evaluate a “feature op version” expression.
