Struct ReceivedDatagram 

pub struct ReceivedDatagram {
    pub bytes_received: usize,
    pub source: SocketAddrV4,
    pub truncated: bool,
}

The result of a successful TransportSocket::recv_from.

truncated is set if the backend delivered only a prefix of the incoming datagram because it did not fit in the caller’s buffer. If callers use a buffer sized to crate::UDP_BUFFER_SIZE, truncation is generally not expected on backends whose delivered datagrams are bounded by that configured application-level cap. Backends that may deliver larger datagrams should surface this explicitly instead of silently dropping the fact that data was discarded.

Note: the default Tokio backend currently always reports truncated: false because tokio::net::UdpSocket::recv_from does not expose MSG_TRUNC (or equivalent). Reliable truncation detection requires a backend that does — e.g. a recvmsg-based backend, or a no_std stack like smoltcp / embassy-net that surfaces the original datagram length.

Fields

bytes_received: usize

Number of bytes written to the caller’s buffer.

source: SocketAddrV4

Source address of the datagram.

truncated: bool

true if the incoming datagram was larger than the caller’s buffer and the tail was discarded. See the type-level docs for the default Tokio backend’s caveat.
