Struct PacketMeta

Source

pub struct PacketMeta {
    pub timestamp_ns: u64,
    pub captured_len: u32,
    pub flow_key: Option<FlowKey>,
    pub tcp_flags: u8,
}

Expand description

Packet metadata extracted for filter evaluation.

flow_key is None for non-IP frames (e.g. ARP). tcp_flags is 0 for non-TCP traffic.

Fields§

§timestamp_ns: u64

Packet timestamp in nanoseconds since the Unix epoch.

§captured_len: u32

Number of captured bytes (without the record header).

§flow_key: Option<FlowKey>

Parsed 5-tuple; None for non-IP or unrecognised frames.

§tcp_flags: u8

TCP control flags; 0 when the transport is not TCP.
