This is a no_std library for ELF file handling. It supports ELF32 and ELF64 format.
To read an elf file, supply elf_rs::Elf
with a &[u8]
memory:
extern crate elf_rs;
use std::io::Read;
use std::fs::File;
use std::env;
use elf_rs::*;
fn read_elf(filename: &String) {
let mut elf_file = File::open(filename).expect("open file failed");
let mut elf_buf = Vec::<u8>::new();
elf_file.read_to_end(&mut elf_buf).expect("read file failed");
let elf = Elf::from_bytes(&elf_buf).expect("load elf file failed");
println!("{:?} header: {:?}", elf, elf.elf_header());
for p in elf.program_header_iter() {
println!("{:x?}", p);
}
for s in elf.section_header_iter() {
println!("{:x?}", s);
}
let s = elf.lookup_section(b".text");
println!("s {:?}", s);
}
Under example directory there is a demo readelf
to read an ELF file.
$ cargo run --example readelf <path_to_elf_file>
