Validity

Enum Validity 

Source
pub enum Validity {
    Valid,
    MaybeValid,
    Invalid,
}
Expand description

Validity of a plan.

Note that there is a one-to-one correspondence with Level. The only difference between Level and Validity is that the variant names for Level are more sensible in the context of a diagnostic, while the names for Validity are more sensible when talking about a validation result as a whole.

Variants§

§

Valid

The plan is valid.

§

MaybeValid

The plan may or may not be valid; the validator was not able to prove or disprove validity.

§

Invalid

The plan is invalid.
