pub fn rfc9421_verify_with_policy<B, F>(
    req: &Request<B>,
    policy: &VerifyPolicy,
    now: DateTime<Utc>,
    resolve_key: F,

where

Errors

Same as rfc9421_verify plus Error::TimestampTooOld, Error::TimestampInFuture, Error::TimestampExpired and Error::TimestampMissing when the policy is violated.
