multiboot2

Rust library that helps you to parse the multiboot information structure (mbi) from Multiboot2-compliant bootloaders, like GRUB. It supports all tags from the specification including full support for the sections of ELF-64 files. This library is no_std and can be used in a Multiboot2-kernel.

It follows the Multiboot 2.0 specification at https://www.gnu.org/software/grub/manual/multiboot2/multiboot.html and the ELF 64 specification at http://www.uclibc.org/docs/elf-64-gen.pdf.

Background: The Multiboot 2 Information Structure

The Multiboot information structure looks like this:

Field	Type
total size	u32
reserved	u32
tags	variable
end tag = (0, 8)	(u32, u32)

There are many different types of tags, but they all have the same beginning:

Field	Type
type	u32
size	u32
other fields	variable

All tags and the mbi itself are 8-byte aligned. The last tag must be the end tag, which is a tag of type 0 and size 8.

MSRV

The MSRV is 1.56.1 stable.
