Struct Route 

#[non_exhaustive]
pub struct Route { /* private fields */ }

The way to one network: a copy of the table’s row, which Table::lookup and Table::routes hand out.

Its fields are the table’s bookkeeping, so they are read through its getters, and only the table’s own calls change the row: a direct route stays direct, and the flap count and timestamps stay the table’s. Build one with Route::direct or Route::learned, to compare with what a lookup returns. It is #[non_exhaustive].

Implementations

impl Route

pub const fn direct(port: PortId) -> Route

A directly attached network on port.

pub const fn learned(port: PortId, next_hop: Mac, now: Instant) -> Route

A network reached through next_hop on port, confirmed now.

pub const fn port(&self) -> PortId

The port the network is reached through.

pub const fn is_direct(&self) -> bool

Whether the network is attached to that port, rather than reached through another router.

pub const fn next_hop(&self) -> &Mac

The next router’s MAC on that port; empty for a direct route.

pub const fn last_seen(&self) -> Option<Instant>

When learning or management last confirmed the route; None for a direct route. Aging keys off it.

pub const fn last_used(&self) -> Option<Instant>

When the route last carried traffic; None until it does, and again after a move to another port. It never extends the route’s life.

pub const fn reachability(&self) -> Reachability

The stored state. A lapsed busy mark still reads Busy here until the sweep; Table::effective_reachability reads it at a time.

pub const fn busy_until(&self) -> Option<Instant>

When a busy mark lapses.

pub const fn flap_count(&self) -> u8

Moves to another port within 60 s of the one before.

pub const fn last_port_change(&self) -> Option<Instant>

When the route last moved to another port.
