Enum feature_check::defs::Mode

#[non_exhaustive]
pub enum Mode {
    List,
    Single(Box<dyn Calculable + 'static>),
    Simple(Box<dyn Calculable + 'static>),
}

The feature-check operating mode, usually “List”.

Variants (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.

List

Obtain the list of the program’s features.

Single(Box<dyn Calculable + 'static>)

Obtain the value of a single feature.

Simple(Box<dyn Calculable + 'static>)

Evaluate a “feature op version” expression.
