//! # `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 object files and some executable files.
//!
//! ## Raw struct definitions
//!
//! Raw structs are defined for: [ELF](elf), [Mach-O](macho), [PE/COFF](pe), [archive].
//! Types and traits for zerocopy support are defined in [pod] and [endian].
//!
//! ## Unified read API
//!
//! The [read::Object] trait defines the unified interace. This trait is implemented
//! by [read::File], which allows reading any file format, as well as implementations
//! for each file format: [ELF](read::elf::ElfFile), [Mach-O](read::macho::MachOFile),
//! [COFF](read::coff::CoffFile), [PE](read::pe::PeFile), [Wasm](read::wasm::WasmFile).
//!
//! ## Low level read API
//!
//! In addition to the unified read API, the various `read` modules define helpers that
//! operate on the raw structs. These also provide traits that abstract over the differences
//! between 32-bit and 64-bit versions of the file format.
//!
//! ## Unified write API
//!
//! [write::Object] allows building a COFF/ELF/Mach-O object and then writing it out.
//!
//! ## Low level executable writers
//!
//! [write::elf::Writer] and [write::pe::Writer] allow writing executable files.
//!
//! ## Example for unified read API
//!  ```no_run
//! # #[cfg(feature = "read")]
//! 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>> {
//! # #[cfg(all(feature = "read", feature = "std"))] {
//!   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(())
//! }
//! ```
