Crate object_rewrite

A library for rewriting object and executable files.

Use the Rewriter struct to read a file, modify it, and write it back. Modifications can be performed using methods on the Rewriter struct, or by passing an Options struct to the Rewriter::modify method.

Currently, only ELF files are supported, and not many modifications are possible yet.

Example

use object_rewrite::{Options, Rewriter};

fn main() -> Result<(), Box<dyn std::error::Error>> {
  let mut options = Options::default();
  options.delete_symbols.insert(b"main".to_vec());

  let input = std::fs::read("path/to/input")?;
  let mut rewriter = Rewriter::read(&input)?;
  rewriter.modify(options)?;
  let mut output = std::fs::File::create("path/to/output")?;
  rewriter.write(&mut output)?;
  Ok(())
}
