Enum guppy::graph::UnknownStatus

#[non_exhaustive]pub enum UnknownStatus {
    Unknown,
    OptionalPresent,
    OptionalUnknown,
}

More information about a dependency or feature whose evaluation is unknown.

If the result of evaluating a dependency or feature is unknown, this enum specifies why.

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.

Unknown

Whether this dependency or feature is present by default or optionally is unknown.

OptionalPresent

This dependency or feature is present optionally, but whether it is included by default is unknown.

OptionalUnknown

This dependency or feature is not present by default, and whether it is included optionally is unknown.
