Enum VersionBinding 

#[non_exhaustive]
pub enum VersionBinding {
    IfPresent,
    Required,
}

Whether a signature must name the version it was made for.

minisign signs a trusted comment along with the file. When it carries a version:<semver> token (see verify::signed_version), the engine checks it against the version the file is supposed to be: the release version for a full artifact, the target version for a delta. That stops an older, validly signed artifact from being served as a newer one.

Sparkle-style Ed25519 signatures sign the file alone and cannot name a version; on macOS, BundleVersion covers them instead.

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.

IfPresent

Check the version: token when a verified signature carries one.

Required

Reject a verified signature without a version: token. Use once every artifact you publish is signed with one.
