Function engine_io_parser::binary::encoder::encode_payload

pub fn encode_payload<'a>(input: &'a [Packet]) -> Vec<u8>

Encode a payload containing multiple packets with either binary or string data to a byte array. In an encoded payload, each packet is denoted with its length and its data type; either binary or string. This function passes binary packet data as is, and encodes string packets to bytes.

Arguments

• input - A list of Packets with either string or binary data each

Example

use engine_io_parser::packet::{Packet, PacketData, PacketType};
use engine_io_parser::binary::encoder::*;

assert_eq!(
   encode_payload(&[
       Packet {
           packet_type: PacketType::Message,
           data: "€".into(),
       },
       Packet {
           packet_type: PacketType::Message,
           data: vec![1u8, 2u8, 3u8, 4u8].into()
       }
   ]),
   b"\x00\x04\xff\x34\xe2\x82\xac\x01\x05\xff\x04\x01\x02\x03\x04"
);
