Struct ChannelData 

pub struct ChannelData<'a> { /* private fields */ }

The ChannelData Message

The ChannelData message is used to carry application data between the client and the server.

The Channel Number field specifies the number of the channel on which the data is traveling, and thus, the address of the peer that is sending or is to receive the data.

The Length field specifies the length in bytes of the application data field (i.e., it does not include the size of the ChannelData header). Note that 0 is a valid length.

The Application Data field carries the data the client is trying to send to the peer, or that the peer is sending to the client.

Implementations

impl<'a> ChannelData<'a>

pub fn new(number: u16, bytes: &'a [u8]) -> Self

pub fn number(&self) -> u16

pub fn bytes(&self) -> &'a [u8]

pub fn message_size(bytes: &[u8], is_tcp: bool) -> Result<usize, Error>

Test

use bytes::{BufMut, BytesMut};
use turn_server::codec::channel_data::ChannelData;

let data: [u8; 4] = [0x40, 0x00, 0x00, 0x40];
let mut bytes = BytesMut::with_capacity(1500);

ChannelData::new(16384, &data[..]).encode(&mut bytes);

let size = ChannelData::message_size(&bytes[..], false).unwrap();

assert_eq!(size, 8);

pub fn encode(self, bytes: &mut BytesMut)

Test

use bytes::{BufMut, BytesMut};
use turn_server::codec::channel_data::ChannelData;

let data: [u8; 4] = [0x40, 0x00, 0x00, 0x40];
let mut bytes = BytesMut::with_capacity(1500);

ChannelData::new(16384, &data[..]).encode(&mut bytes);

let ret = ChannelData::decode(&bytes[..]).unwrap();

assert_eq!(ret.number(), 16384);
assert_eq!(ret.bytes(), &data[..]);

pub fn decode(bytes: &'a [u8]) -> Result<Self, Error>

Test

use bytes::{BufMut, BytesMut};
use turn_server::codec::channel_data::ChannelData;

let data: [u8; 4] = [0x40, 0x00, 0x00, 0x40];
let mut bytes = BytesMut::with_capacity(1500);

ChannelData::new(16384, &data[..]).encode(&mut bytes);

let ret = ChannelData::decode(&bytes[..]).unwrap();

assert_eq!(ret.number(), 16384);
assert_eq!(ret.bytes(), &data[..]);
