Struct NeighborCache 

pub struct NeighborCache<'d> { /* private fields */ }

The stack’s neighbor cache, returned by Stack::neighbor_cache.

Implementations

impl<'d> NeighborCache<'d>

pub fn get(&self, iface: IfaceHandle, addr: IpAddress) -> Option<Neighbor>

Look up a neighbor by interface and IP address.

pub fn iter(&self) -> impl Iterator<Item = Neighbor> + 'd

Iterate over the neighbors in the cache.

pub fn insert( &self, iface: IfaceHandle, addr: IpAddress, hardware_addr: HardwareAddress, expires_at: Instant, )

Insert a neighbor, replacing any entry for the same interface and address.

pub fn remove(&self, iface: IfaceHandle, addr: IpAddress) -> Option<Neighbor>

Remove a neighbor, returning it.

pub fn retain(&self, f: impl FnMut(&Neighbor) -> bool)

Keep only the neighbors f returns true for.

pub fn clear_iface(&self, iface: IfaceHandle)

Remove every neighbor on one interface.

pub fn clear(&self)

Remove every neighbor.

pub fn len(&self) -> usize

The number of neighbors in the cache.

pub fn is_empty(&self) -> bool

Whether the cache is empty.
