Struct PacketMetadata

pub struct PacketMetadata {
    pub src_ip: Ipv4Address,
    pub dst_ip: Ipv4Address,
    pub src_port: Port,
    pub dst_port: Port,
    pub protocol: Protocol,
    pub tcp_flags: u8,
    pub conn_state: Option<ConntrackState>,
    pub packet_len: u16,
}

Expand description

Extracted packet metadata used for rule evaluation

This avoids passing raw packet bytes – the caller extracts relevant header fields before calling the firewall engine.

Fields§

§src_ip: Ipv4Address

Source IPv4 address

§dst_ip: Ipv4Address

Destination IPv4 address

§src_port: Port

Source port (0 for ICMP)

§dst_port: Port

Destination port (0 for ICMP)

§protocol: Protocol

IP protocol

§tcp_flags: u8

TCP flags (raw byte)

§conn_state: Option<ConntrackState>

Connection tracking state (if known)

§packet_len: u16

Total packet length in bytes
