//! Rust library with type definitions and parsing functions for Multiboot2
//! headers, as well as a builder to build them at runtime. This library is
//! `no_std` and can be used in bootloaders.
//!
//! # Example
//!
//! ```rust
//! use multiboot2_header::builder::{InformationRequestHeaderTagBuilder, HeaderBuilder};
//! use multiboot2_header::{HeaderTagFlag, HeaderTagISA, MbiTagType, RelocatableHeaderTag, RelocatableHeaderTagPreference, Multiboot2Header};
//!
//! // Small example that creates a Multiboot2 header and parses it afterwards.
//!
//! // We create a Multiboot2 header during runtime here. A practical example is that your
//! // program gets the header from a file and parses it afterwards.
//! let mb2_hdr_bytes = HeaderBuilder::new(HeaderTagISA::I386)
//!     .relocatable_tag(RelocatableHeaderTag::new(
//!         HeaderTagFlag::Required,
//!         0x1337,
//!         0xdeadbeef,
//!         4096,
//!         RelocatableHeaderTagPreference::None,
//!     ))
//!     .information_request_tag(
//!         InformationRequestHeaderTagBuilder::new(HeaderTagFlag::Required)
//!             .add_irs(&[MbiTagType::Cmdline, MbiTagType::BootLoaderName]),
//!     )
//!     .build();
//!
//! // Cast bytes in vector to Multiboot2 information structure
//! let mb2_hdr = unsafe { Multiboot2Header::load(mb2_hdr_bytes.as_ptr().cast()) };
//! println!("{:#?}", mb2_hdr);
//!
//! ```
//!
//! ## MSRV
//!
//! The MSRV is 1.69.0 stable.
