Struct RouterConnection 

pub struct RouterConnection { /* private fields */ }

A KNXnet/IP router connection over multicast UDP.

Implementations

impl RouterConnection

pub async fn connect( local_addr: Ipv4Addr, multicast: SocketAddrV4, ) -> Result<Self, KnxIpError>

Join the KNX multicast group and start receiving routing indications.

local_addr is the local interface to bind to (use 0.0.0.0 for any). multicast is the multicast group + port (default 224.0.23.12:3671).

Errors

Returns KnxIpError if the socket cannot be created or joined.

pub async fn connect_v4( local_addr: Ipv4Addr, multicast: SocketAddrV4, ) -> Result<Self, KnxIpError>

Join an IPv4 KNX multicast group and start receiving routing indications.

Errors

Returns KnxIpError if the socket cannot be created or joined.

pub async fn connect_v6( interface: u32, multicast: SocketAddrV6, ) -> Result<Self, KnxIpError>

Join an IPv6 multicast group and start receiving routing indications.

Use the target address scope id or pass an explicit interface index for link-local multicast groups.

Errors

Returns KnxIpError if the socket cannot be created or joined.

pub async fn connect_multicast( multicast: SocketAddr, ) -> Result<Self, KnxIpError>

Join a KNX multicast group from a generic socket address.

IPv4 uses 0.0.0.0 as the interface selector. IPv6 uses the target scope id as the interface index when present.

Errors

Returns KnxIpError if the socket cannot be created or joined.

pub async fn connect_default(local_addr: Ipv4Addr) -> Result<Self, KnxIpError>

Connect to the default KNX multicast group (224.0.23.12:3671).

Errors

Returns KnxIpError if the socket cannot be created.

Trait Implementations

impl KnxConnection for RouterConnection

fn send(&self, frame: CemiFrame) -> KnxFuture<'_, Result<(), KnxIpError>>

Send a CEMI frame to the KNX bus.

fn recv(&mut self) -> KnxFuture<'_, Option<CemiFrame>>

Receive the next CEMI frame from the KNX bus.

fn close(&mut self) -> KnxFuture<'_, ()>

Close the connection gracefully.
