Enum CoverageError 

#[non_exhaustive]
pub enum CoverageError {
    Missing,
    Ambiguous,
    Invalid(&'static str),
    Unlisted,
}

Why the coverage question cannot be answered. A guard that cannot answer fails, unlike the verifier, whose contract is fail-open.

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.

Missing

The tree holds no spec.

Ambiguous

Both locations hold one.

Invalid(&'static str)

The spec at this path is unreadable or invalid.

Unlisted

git could not list the tree, or it is empty.
