Expand description


A minimal and fast zero-copy parser for the PE32+ file format.

Build status


This project aims to offer a more light weight and easier to use alternative to fully featured binary parsing libraries when it comes to parsing the PE32+ file format. It does so by:

  • Taking a zero-copy approach. Everything is a reference to the original data
  • Parsing on demand. Basic parsing is done at the beginning, the rest is opt-in
  • Not focusing on endianness. The parsed buffer is assumed to be in LE
  • Strongly validating native structures according to the official specification
  • Having no external dependencies on top of being a no-std library


Example of printing the RVA’s and names of imported symbols:

use peview::{dir::Import, file::PeView};
use std::{error::Error, fs::File, io::Read};

fn main() -> Result<(), Box<dyn Error>> {
    // Read file into buffer and parse it
    let mut buf = Vec::new();
    File::open("etc/exe/ntoskrnl.exe")?.read_to_end(&mut buf)?;
    let pe = PeView::parse(&buf)?;

    // Iterate over modules in the import table
    for m in pe.imports()? {
        // Print the current modules name
        let module = m?;

        // Iterate over symbols within the module
        for i in module {
            // Check if the symbol is imported by name
            if let Import::Name(h, n) = i? {
                // Print out both the hint and its name
                println!("> {:#04x}: {}", h, n);
