object
The object
crate provides a unified interface to working with object files
across platforms. It supports reading relocatable object files and executable files,
and writing COFF/ELF/Mach-O/XCOFF relocatable object files and ELF/PE executable files.
For reading files, it provides multiple levels of support:
- raw struct definitions suitable for zero copy access
- low level APIs for accessing the raw structs (example)
- a higher level unified API for accessing common features of object files, such as sections and symbols (example)
Supported file formats for reading: ELF, Mach-O, Windows PE/COFF, Wasm, XCOFF, and Unix archive.
For writing files, it provides:
- low level writers for ELF, PE, and COFF
- higher level builder for ELF (example)
- a unified API for writing relocatable object files (ELF, Mach-O, COFF, XCOFF) (example)
Example for unified read API
use object::{Object, ObjectSection};
use std::error::Error;
use std::fs;
/// Reads a file and displays the name of each section.
fn main() -> Result<(), Box<dyn Error>> {
let binary_data = fs::read("path/to/binary")?;
let file = object::File::parse(&*binary_data)?;
for section in file.sections() {
println!("{}", section.name()?);
}
Ok(())
}
