Struct UdpMulticastRadio 

pub struct UdpMulticastRadio { /* private fields */ }

Host-side radio simulator backed by UDP multicast.

Raw UMSH frames are sent and received over IPv4 multicast with no additional framing. Multicast loopback is enabled by default so that multiple processes on the same host can exchange frames via the loopback interface.

Because multicast loopback echoes every sent frame back to the sender, UdpMulticastRadio stores the last transmitted frame and silently drops any received frame that is an exact byte-for-byte match. A legitimately forwarded copy of the frame is never an exact match: repeaters always modify the packet (decrementing the hop count or removing a source-route entry), so only the loopback echo is affected.

Implementations

impl UdpMulticastRadio

pub async fn bind_v4( group_addr: Ipv4Addr, port: u16, ) -> Result<Self, UdpMulticastRadioError>

Bind a UDP multicast simulator socket using a simple localhost-oriented configuration.

pub async fn bind_with_config( config: UdpMulticastRadioConfig, ) -> Result<Self, UdpMulticastRadioError>

Bind a UDP multicast simulator socket using the provided configuration.
