Struct elfio::NoteSectionAccessor

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

A section data accessor intended to note sections

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/hello_32")?;
    let mut reader = BufReader::new(elf_file);

    let mut elf = Elfio::new();

    elf.load(&mut reader)?;

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

    let notes = elfio::NoteSectionAccessor::new(&elf, section);

    assert_eq!(notes.get_notes_num(), 1);

    let note = notes.get_note(0).unwrap();
    assert_eq!(note.ntype, 1);
    assert_eq!(note.name, "GNU");
    assert_eq!(
        note.description,
        vec![0u8, 0u8, 0u8, 0u8, 2u8, 0u8, 0u8, 0u8, 6u8, 0u8, 0u8, 0u8, 9u8, 0u8, 0u8, 0u8]
    );

    Ok(())
}
