## 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](https://learn.microsoft.com/en-us/windows/win32/debug/pe-format)
- Having no external dependencies on top of being a `no-std` library
## Usage
Example of printing the RVA's and names of imported symbols:
```rust
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?;
println!("{}", module.name()?);
// 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);
}
}
}
Ok(())
}
```
