object

The object crate provides a unified interface to working with object files across platforms. It supports reading object files and executable files, and writing COFF/ELF/Mach-O 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: ELF, Mach-O, Windows PE/COFF, Wasm, and Unix archive.

Example for unified read API

use object::{Object, ObjectSection};
use std::error::Error;
use std::fs;

/// Reads a file and displays the content of the ".boot" section.
fn main() -> Result<(), Box<dyn Error>> {
  let bin_data = fs::read("./multiboot2-binary.elf")?;
  let obj_file = object::File::parse(&*bin_data)?;
  if let Some(section) = obj_file.section_by_name(".boot") {
    println!("{:#x?}", section.data()?);
  } else {
    eprintln!("section not available");
  }
  Ok(())
}
