Module nud

Neighbor Unreachability Detection.

Structs

• ConfirmationFlags
  Neighbor confirmation flags.
• Delay
  State associated with a neighbor in delay state.
• Event
  Neighbor event.
• Incomplete
  The state for an incomplete neighbor entry.
• NeighborApi
  The neighbor API.
• NudCountersInner
  NUD counters.
• NudState
  NUD module per-device state.
• NudTimerId
  The timer ID for the NUD module.
• NudUserConfig
  NUD configurations.
• NudUserConfigUpdate
  An update structure for NudUserConfig.
• Reachable
  State associated with a reachable neighbor.
• Stale
  State associated with a stale neighbor.

Enums

• DynamicNeighborState
  The state of a dynamic entry in the neighbor cache within the Neighbor Unreachability Detection state machine, defined in RFC 4861 section 7.3.2 and RFC 7048 section 3.
• DynamicNeighborUpdateSource
  The type of message with a dynamic neighbor update.
• EventDynamicState
  The state of dynamic neighbor table entries as published via events.
• EventKind
  Neighbor event kind.
• EventState
  Neighbor state published via events.
• LinkResolutionResult
  Specifies the link-layer address of a neighbor.
• NeighborRemovalError
  Error when a neighbor table entry cannot be removed.
• NeighborState
  A neighbor’s state.
• StaticNeighborInsertionError
  Error when a static neighbor entry cannot be inserted.

Constants

• MAX_ENTRIES
  The maximum number of neighbor entries in the neighbor table for a given device. When the number of entries is above this number and an entry transitions into a discardable state, a garbage collection task will be scheduled to remove any entries that are not in use.
• RETRANS_TIMER_DEFAULT
  The default value for RetransTimer as defined in RFC 4861 section 10.

Traits

• DelegateNudContext
  Enables a blanket implementation of NudContext via delegate that can wrap a mutable reference of Self.
• LinkResolutionContext
  An execution context that allows creating link resolution notifiers.
• LinkResolutionNotifier
  A notifier held by core that can be used to inform interested parties of the result of link address resolution.
• NudBindingsContext
  The bindings context for NUD.
• NudBindingsTypes
  A marker trait for types provided by bindings to NUD.
• NudConfigContext
  The execution context for NUD that allows accessing NUD configuration (such as timer durations) for a particular device.
• NudContext
  The execution context for NUD for a link device.
• NudHandler
  An implementation of NUD for a link device.
• NudIcmpContext
  The execution context which allows sending ICMP destination unreachable errors, which needs to happen when address resolution fails.
• NudIpHandler
  An implementation of NUD for the IP layer.
• NudSenderContext
  The execution context for NUD for a link device that allows sending IP packets to specific neighbors.
• UseDelegateNudContext
  A marker trait to enable the blanket impl of NudContext for types implementing DelegateNudContext.

Functions

• confirm_reachable
  Confirm upper-layer forward reachability to the specified neighbor through the specified device.

Type Aliases

• NudCounters
  NUD counters.
