Enum feature_check::defs::CalcResult

#[non_exhaustive]
pub enum CalcResult {
    Null,
    Bool(bool),
    Version(Version),
}

The result of evaluating either a single term or the whole expression.

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.

Null

No value, e.g. the queried feature is not present.

Bool(bool)

A boolean value, usually for the whole expression.

Version(Version)

A feature’s obtained version.
