Rust TLP库

这个crate提供了解析PCI TLP数据包的struct和函数。

示例

use rtlp_lib::TlpPacket;
use rtlp_lib::TlpFmt;
use rtlp_lib::TlpType;
use rtlp_lib::new_msg_req;
use rtlp_lib::new_conf_req;
use rtlp_lib::new_mem_req;
use rtlp_lib::new_cmpl_req;

// Bytes for full TLP Packet
//               <------- DW1 -------->  <------- DW2 -------->  <------- DW3 -------->  <------- DW4 -------->
let bytes = vec![0x00, 0x00, 0x20, 0x01, 0x04, 0x00, 0x00, 0x01, 0x20, 0x01, 0xFF, 0x00, 0xC2, 0x81, 0xFF, 0x10];
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();

// Get requester_id field from this TLP (TLP can be of different types)
let requester_id;
