Struct FlowAttribution 

pub struct FlowAttribution {
    pub src_addr: Option<String>,
    pub src_port: Option<u16>,
    pub dst_addr: Option<String>,
    pub dst_port: Option<u16>,
    pub protocol: Option<String>,
    pub protocol_byte: Option<u8>,
}

L3/L4 attribution distilled from an nflog payload.

All fields are optional because nflog can be configured with copy-mode META (no payload at all) or because the captured packet may be a non-IP frame (very rare in practice — netfilter only hooks IP).

L5-15: src_addr / src_port / protocol_byte are populated alongside the dst fields so the listener can derive a FlowKey suitable for FlowAccumulator::record(). The wire-emitted NetworkFlowDecision schema only carries dst attribution today, so the src fields are listener-internal — they exist on this struct to keep one parsing pass rather than re-walking the payload.

Fields

src_addr: Option<String>

src_port: Option<u16>

dst_addr: Option<String>

dst_port: Option<u16>

protocol: Option<String>

protocol_byte: Option<u8>

IANA protocol byte (6 = TCP, 17 = UDP, 1 = ICMP, 58 = ICMPv6). Kept alongside the human-readable protocol string so the FlowKey hash stays cheap and matches the FlowKey::protocol: u8 field directly.

Trait Implementations

impl Clone for FlowAttribution

fn clone(&self) -> FlowAttribution

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FlowAttribution

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FlowAttribution

fn default() -> FlowAttribution

Returns the “default value” for a type.

impl PartialEq for FlowAttribution

fn eq(&self, other: &FlowAttribution) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
