Struct NeighborEntry 

#[non_exhaustive]
pub struct NeighborEntry {
    pub id: Id<NeighborEntry>,
    pub interface_index: u32,
    pub address: IpAddress,
    pub mac: Option<MacAddress>,
    pub state: NeighborState,
}

A single entry in the system’s neighbor table (ARP for IPv4, NDP for IPv6): the mapping from an on-link IP address to a link-layer (MAC) address, as observed or configured on a given interface.

#[non_exhaustive]: platforms carry different neighbor fields (Linux exposes NUD state and a routing-protocol-style entry kind; BSD/macOS expose only a flags word; Windows exposes IsRouter/reachability timestamps). Marking this non-exhaustive now means adding platform-specific fields later is not a breaking change for consumers who construct a NeighborEntry via NeighborEntry::new rather than a struct literal — see ARCHITECTURE.md’s note on model extensibility.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: Id<NeighborEntry>

interface_index: u32

The OS-level interface index this entry was observed on, the same raw value Interface::index/Route::interface_index carry.

address: IpAddress

mac: Option<MacAddress>

Absent for an entry still being resolved (NeighborState::Incomplete) or one the platform reports without a link-layer address at all.

state: NeighborState
