Function new_mem_req

pub fn new_mem_req(bytes: Vec<u8>, format: &TlpFmt) -> Box<dyn MemRequest>

Obtain Memory Request trait from bytes in vector as dyn This is preffered way of dealing with TLP headers as exact format (32/64 bits) is not required

Examples

use std::convert::TryFrom;

use rtlp_lib::TlpPacket;
use rtlp_lib::TlpFmt;
use rtlp_lib::MemRequest;
use rtlp_lib::new_mem_req;

let bytes = vec![0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00];
let tlp = TlpPacket::new(bytes);

if let Ok(tlpfmt) = TlpFmt::try_from(tlp.get_tlp_format()) {
    // MemRequest contain only fields specific to PCI Memory Requests
    let mem_req: Box<dyn MemRequest> = new_mem_req(tlp.get_data(), &tlpfmt);

    // Address is 64 bits regardles of TLP format
    //println!("Memory Request Address: {:x}", mem_req.address());

    // Format of TLP (3DW vs 4DW) is stored in the TLP header
    println!("This TLP size is: {}", tlpfmt);
    // Type LegacyIO vs MemRead vs MemWrite is stored in first DW of TLP
    println!("This TLP type is: {}", tlp.get_tlp_type());
