Struct TlpPacket

pub struct TlpPacket { /* private fields */ }

TLP Packet structure is high level abstraction for entire TLP packet Contains Header and Data

Examples

use rtlp_lib::TlpPacket;

use rtlp_lib::new_msg_req;

use rtlp_lib::new_mem_req;
use rtlp_lib::new_cmpl_req;

// Bytes for full TLP Packet
//               <------- DW1 -------->  <------- DW2 -------->  <------- DW3 -------->  <------- DW4 -------->

let packet = TlpPacket::new(bytes);

let header = packet.get_header();
// TLP Type tells us what is this packet
let tlp_type = header.get_tlp_type().unwrap();
let tlp_format = packet.get_tlp_format();
