Expand description

peview

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

Goal

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

Usage

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

// Read target file into buffer
let mut buf = Vec::new();
File::open("etc/ntoskrnl.exe")?.read_to_end(&mut buf)?;
// Initialize the parser, does basic validation
let pe = PeView::parse(&buf)?;

// Iterate over modules in the import table
for m in pe.imports()? {
    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);
        }
    }
}
