1# `object`
2
3The `object` crate provides a unified interface to working with object files
4across platforms. It supports reading object files and executable files,
5and writing COFF/ELF/Mach-O object files and ELF/PE executable files.
6
7For reading files, it provides multiple levels of support:
8
9* raw struct definitions suitable for zero copy access
10* low level APIs for accessing the raw structs ([example](crates/examples/src/readobj/))
11* a higher level unified API for accessing common features of object files, such
12 as sections and symbols ([example](crates/examples/src/objdump.rs))
13
14Supported file formats: ELF, Mach-O, Windows PE/COFF, Wasm, and Unix archive.
15
16## Example for unified read API
17```rust
18use object::{Object, ObjectSection};
19use std::error::Error;
20use std::fs;
21
22/// Reads a file and displays the content of the ".boot" section.
23fn main() -> Result<(), Box<dyn Error>> {
24 let bin_data = fs::read("./multiboot2-binary.elf")?;
25 let obj_file = object::File::parse(&*bin_data)?;
26 if let Some(section) = obj_file.section_by_name(".boot") {
27 println!("{:#x?}", section.data()?);
28 } else {
29 eprintln!("section not available");
30 }
31 Ok(())
32}
33```
