Lightweight, memory-safe, zero-allocation library for reading and navigating PE binaries.
The purpose of this library is inspecting PE binaries (whether on disk or already loaded in memory).
A trade-off was made to not unify the 32-bit (PE32) and 64-bit (PE32+) formats for two reasons:
-
There are small but incompatible differences, which would add overhead by requiring constant matching even if at source code level the match arms look identical.
-
Most of the time you know (at build time) what format you're working with anyway.
This makes it rather awkward to work with both formats together transparently.
Note that while the correct name is PE32+, the name PE64 is used as it is a valid identifier; they are otherwise synonymous.
Included are bins showing some uses for the library, try them out on the demos!
This library is available on crates.io.
Documentation can be found on docs.rs.
In your Cargo.toml, put
[dependencies]
pelite = "0.8"
Try this example: cargo run --example readme.
use pelite::FileMap;
use pelite::pe64::{Pe, PeFile};
fn main() {
// Load the desired file into memory
let file_map = FileMap::open("demo/Demo64.dll").unwrap();
// Process the image file
dll_deps(file_map.as_ref()).unwrap();
}
fn dll_deps(image: &[u8]) -> pelite::Result<()> {
// Interpret the bytes as a PE32+ executable
let file = PeFile::from_bytes(image)?;
// Let's read the DLL dependencies
let imports = file.imports()?;
for desc in imports {
// Get the DLL name being imported from
let dll_name = desc.dll_name()?;
// Get the number of imports for this dll
let iat = desc.iat()?;
println!("imported {} functions from {}", iat.len(), dll_name);
}
Ok(())
