Crate elfio[−][src]

Expand description

‘elfio’ is a Rust library intended for reading and generation files in the ELF binary format. The library supports processing of ELF files for 32- and 64-bit architectures regardless of their endianess

For example:

use std::fs::File;
use std::io;
use std::io::BufReader;

use elfio::Elfio;

fn main() -> io::Result<()> {
    let elf_file = File::open("tests/files/hello_64")?;
    let mut file_reader = BufReader::new(elf_file);

    let mut elf = elfio::Elfio::new();

    elf.load(&mut file_reader)?;

    match elf.get_type() {
        elfio::constant::ET_REL => println!("Object ELF file"),
        elfio::constant::ET_EXEC => println!("Executable ELF file"),
        elfio::constant::ET_DYN => println!("Shared library ELF file"),
        elfio::constant::ET_CORE => println!("Core ELF file"),
        _ => println!("ELF type is not recognized"),
    }

    Ok(())
}

Modules

constant

The constants defined by ELF standard and used by ELFIO trait

Structs

Array

An array element

ArraySectionAccessor

A section data accessor intended to array tables. The accessor is useful for manipulation of such sections as .ctors, .dtors, .init_array and .fini_array

Dynamic

A dynamic table element

DynamicSectionAccessor

A section data accessor intended to dynamic tables

Elfio

Elfio - the main struct of the library. All access to ELF files attributes starts from this object. The object provides functions to access ELF file header attributes as well as the list of segments and sections of this file.

ModInfoSectionAccessor

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

Note

A note entry. The note is used by compilers and other tools to mark an object file with special information that has special meaning to a particular tool set.

NoteSectionAccessor

A section data accessor intended to note sections

Relocation

A relocation entry. The relocation contains information that describes how to modify section contents, thus allowing executable and shared object files to hold the right information for a process’s program image.

RelocationSectionAccessor

A section data accessor intended to relocation tables

StringSectionAccessor

A section data accessor intended to string tables

Symbol

A struct represents a single symbol from symbol table section

SymbolSectionAccessor

A section data accessor intended to symbol tables
