Enum VersionError 

#[non_exhaustive]
pub enum VersionError {
    ZeroVersion,
    UnkownVersion(NonZero<u32>),
}

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.

ZeroVersion

UnkownVersion(NonZero<u32>)
