Struct Multiboot2BasicHeader 

pub struct Multiboot2BasicHeader { /* private fields */ }

The fixed prefix of a Multiboot2 header.

This contains only fields with a compile-time-known layout. It is followed by a dynamically sized sequence of header tags, so it is not a complete Multiboot2 header. Use Header to parse the complete header.

Implementations

impl Multiboot2BasicHeader

pub const fn verify_checksum(&self) -> Result<(), (u32, u32)>

Verifies if a Multiboot2 header is valid.

pub const fn calc_checksum(magic: u32, arch: HeaderTagISA, length: u32) -> u32

Calculates the checksum as described in the spec.

pub const fn header_magic(&self) -> u32

Returns the header magic.

pub const fn arch(&self) -> HeaderTagISA

Returns the HeaderTagISA.

pub const fn length(&self) -> u32

Returns the length.

pub const fn checksum(&self) -> u32

Returns the checksum.
