Struct unreliable_message::network::Sender

pub struct Sender {
    pub datagram_length: u16,
    pub replication: u8,
    // some fields omitted
}

The sending end of an unreliable message socket.

Fields

datagram_length: u16

replication: u8

Methods

impl Sender

fn from_socket(
    socket: UdpSocket,
    datagram_length: u16,
    replication: u8
) -> Sender

Constructs a sender from a socket.

• datagram_length is the max-size of a UDP packet.
• replication is the amout of times that a chunk will get re-sent.

replication should almost always be 1, and rarely 2 or above.

fn enqueue<T: ToSocketAddrs>(
    &mut self,
    message: Vec<u8>,
    addrs: T
) -> UnrResult<()>

Adds a message to the queue of chunks to send out.

fn send_one(&mut self) -> UnrResult<bool>

Attempts to send one UDP packet over the network.

The size of the UDP packet is bounded by self.datagram_length.

Returns

• Err(e) if an error occurred during sending.
• Ok(true) if there are more messages in the queue.
• Ok(false) if theere are no more messages in the queue.

fn send_all(&mut self) -> UnrResult<()>

Attemts to send all UDP packets by repeatedly calling send_one.

fn is_queue_empty(&self) -> bool

fn queue_len(&self) -> usize
