# `object`
The `object` crate provides a unified interface to working with object files
across platforms. It supports reading object files and executable files,
and writing COFF/ELF/Mach-O object files and ELF/PE executable files.
For reading files, it provides multiple levels of support:
* raw struct definitions suitable for zero copy access
* low level APIs for accessing the raw structs ([example](crates/examples/src/readobj/))
* a higher level unified API for accessing common features of object files, such
as sections and symbols ([example](crates/examples/src/objdump.rs))
Supported file formats: ELF, Mach-O, Windows PE/COFF, Wasm, and Unix archive.
## Example for unified read API
```rust
use object::{Object, ObjectSection};
use std::error::Error;
use std::fs;
/// Reads a file and displays the content of the ".boot" section.
fn main() -> Result<(), Box<dyn Error>> {
let bin_data = fs::read("./multiboot2-binary.elf")?;
let obj_file = object::File::parse(&*bin_data)?;
if let Some(section) = obj_file.section_by_name(".boot") {
println!("{:#x?}", section.data()?);
} else {
eprintln!("section not available");
}
Ok(())
}
```
See [`crates/examples`](crates/examples) for more examples.
## Minimum Supported Rust Version (MSRV)
Changes to MSRV are considered breaking changes. We are conservative about changing the MSRV,
but sometimes are required to due to dependencies. The MSRV is:
* 1.52.0 for the `read` feature and its dependencies.
* 1.61.0 for the `write` feature and its dependencies.
