Enum NetworkEvent 

pub enum NetworkEvent {
    NewLink(LinkMessage),
    DelLink(LinkMessage),
    NewAddress(AddressMessage),
    DelAddress(AddressMessage),
    NewRoute(RouteMessage),
    DelRoute(RouteMessage),
    NewNeighbor(NeighborMessage),
    DelNeighbor(NeighborMessage),
    NewFdb(FdbEntry),
    DelFdb(FdbEntry),
    NewQdisc(TcMessage),
    DelQdisc(TcMessage),
    NewClass(TcMessage),
    DelClass(TcMessage),
    NewFilter(TcMessage),
    DelFilter(TcMessage),
    NewAction(TcMessage),
    DelAction(TcMessage),
}

Network events that can be received from the kernel.

These events are generated when network configuration changes occur. Use Connection<Route>::subscribe to select which event types to receive, then use Connection::events to get a stream of events.

Implementations

impl NetworkEvent

pub fn is_new(&self) -> bool

Returns true if this is a “new” event (add or change).

pub fn is_del(&self) -> bool

Returns true if this is a “delete” event.

pub fn ifindex(&self) -> Option<u32>

Returns the interface index associated with this event, if any.

pub fn action(&self) -> &'static str

Returns “new” or “del” based on the event type.

Useful for display/logging purposes.

pub fn as_link(&self) -> Option<&LinkMessage>

Returns the inner LinkMessage if this is a link event.

pub fn into_link(self) -> Option<LinkMessage>

Consumes self and returns the inner LinkMessage if this is a link event.

pub fn as_address(&self) -> Option<&AddressMessage>

Returns the inner AddressMessage if this is an address event.

pub fn into_address(self) -> Option<AddressMessage>

Consumes self and returns the inner AddressMessage if this is an address event.

pub fn as_route(&self) -> Option<&RouteMessage>

Returns the inner RouteMessage if this is a route event.

pub fn into_route(self) -> Option<RouteMessage>

Consumes self and returns the inner RouteMessage if this is a route event.

pub fn as_neighbor(&self) -> Option<&NeighborMessage>

Returns the inner NeighborMessage if this is a neighbor event.

pub fn into_neighbor(self) -> Option<NeighborMessage>

Consumes self and returns the inner NeighborMessage if this is a neighbor event.

pub fn as_fdb(&self) -> Option<&FdbEntry>

Returns the inner FdbEntry if this is an FDB event.

pub fn into_fdb(self) -> Option<FdbEntry>

Consumes self and returns the inner FdbEntry if this is an FDB event.

pub fn as_tc(&self) -> Option<&TcMessage>

Returns the inner TcMessage if this is a TC event (qdisc, class, filter, or action).

pub fn into_tc(self) -> Option<TcMessage>

Consumes self and returns the inner TcMessage if this is a TC event.

Trait Implementations

impl Clone for NetworkEvent

fn clone(&self) -> NetworkEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NetworkEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result
