Struct Pingwave 

Source
#[repr(C)]
pub struct Pingwave { pub origin_id: u64, pub seq: u64, pub ttl: u8, pub hop_count: u8, pub _reserved: [u8; 6], }
Expand description

Pingwave packet for neighbor discovery.

Layout (24 bytes):

┌────────────────────────────────────────────────────────────┐
│ origin_id (8) │ seq (8) │ ttl (1) │ hops (1) │ reserved (6)│
└────────────────────────────────────────────────────────────┘

Fields§

§origin_id: u64

Originating node ID

§seq: u64

Sequence number (monotonic per origin)

§ttl: u8

Time-to-live (usually 2-3 hops)

§hop_count: u8

Hop count so far

§_reserved: [u8; 6]

Reserved for future use
