Struct FlowKey 

pub struct FlowKey {
    pub src_addr: IpAddr,
    pub src_port: u16,
    pub dst_addr: IpAddr,
    pub dst_port: u16,
    pub protocol: u8,
}

5-tuple uniquely identifying an L4 flow. Used as the hash key for counting unique connections exercised by the workload.

protocol is a small numeric (IANA proto byte: 6 = TCP, 17 = UDP, 1 = ICMP, 58 = ICMPv6) rather than a String so the hash key stays cheap to compute and copy. Source addr/port are included so a workload that opens N parallel connections to the same (dst, port) is counted as N flows, matching what exercised_egress_connections promises to consumers (“connections”, not “destinations”).

Fields

src_addr: IpAddr

src_port: u16

dst_addr: IpAddr

dst_port: u16

protocol: u8

Trait Implementations

impl Clone for FlowKey

fn clone(&self) -> FlowKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlowKey

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

Formats the value using the given formatter.

impl Hash for FlowKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FlowKey

fn eq(&self, other: &FlowKey) -> 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.
