SendDatagram

Struct SendDatagram

#[non_exhaustive]
pub struct SendDatagram<'a> { /* private fields */ }

Available on crate features std and udp only.

Expand description

Borrowed description of one outgoing datagram or segmented datagram group.

This type contains UDP packet metadata only. It has no connection, packet number, retransmission, or upper-protocol semantics.

Implementations§

impl<'a> SendDatagram<'a>

pub fn new( destination: impl Into<SocketAddress>, payload: &'a [u8], ) -> SendDatagram<'a>

Construct an ordinary unsegmented datagram.

pub const fn destination(&self) -> SocketAddress

Destination address.

pub const fn payload(&self) -> &'a [u8] ⓘ
