    server_timestamp: &DateTime<Utc>,
    allowed_mismatch: Option<Duration>,

Expand description

Verify a SigV4 request at a particular point-in-time. This verifies that the request timestamp is not beyond the allowed timestamp mismatch against the specified point-in-time, and that the request signature matches our expected signature.

This is mainly for unit testing. For general purpose use, use sigv4_verify.

§Errors

If the request timestamp is outside the allowed timestamp mismatch, a SignatureError::TimestampOutOfRange error is returned.

If the request signature does not match the expected signature, a SignatureError::InvalidSignature error is returned.

§Panics

If the expected signature string is not 64 bytes long, this function will panic. This should never happen.
