Struct elfio::ModInfoSectionAccessor

pub struct ModInfoSectionAccessor<'a> { /* fields omitted */ }

A section data accessor intended to modinfo tables. The accessor is useful for kernel modules data

For example:

use std::fs::File;
use std::io;
use std::io::{BufReader, Error};

use elfio::Elfio;

fn main() -> io::Result<()> {
    let elf_file = File::open("tests/files/i2c-gpio.ko")?;
    let mut reader = BufReader::new(elf_file);

    let mut elf = Elfio::new();

    elf.load(&mut reader)?;

    let section = match elf.get_section_by_name(&".modinfo") {
        Some(s) => s,
        None => return Err(Error::new(io::ErrorKind::Other, "section not found")),
    };

    let modinfo = elfio::ModInfoSectionAccessor::new(&elf, section);

    assert_eq!(modinfo.get_entries_num(), 10);
    assert_eq!(modinfo.get(&"description".to_string()).unwrap(), "Platform-independent bitbanging I2C driver");

    Ok(())
}
