Enum VersionPreference 

#[non_exhaustive]
pub enum VersionPreference {
    Both,
    V1Only,
    V2Only,
}

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.

Both

V1Only

V2Only

Accept only v2 headers. V2 supports CRC32c integrity checks and binary TLVs, making this the stricter option for hardened deployments.
