pub struct PacketMetadata {
pub timestamp: Option<SystemTime>,
}Fields§
§timestamp: Option<SystemTime>The kernel capture timestamp for this packet, if the backend supports it.
On BPF platforms (macOS/BSD/Windows), this is always populated from the
bh_tstamp field in the BPF header, which is set by the kernel when the
packet is captured.
On Linux, this is populated when Config::enable_timestamps is true.
On other backends, this is None.
Comparing this timestamp against SystemTime::now() after next_with_metadata()
returns gives the delay between kernel capture time and application processing time,
which includes any time the packet spent in the receive buffer.
