Struct multiboot2::Tag

source ·
#[repr(C)]
pub struct Tag { pub typ: TagTypeId, pub size: u32, }
Expand description

Common base structure for all tags that can be passed via the Multiboot2 Information Structure (MBI) to a Multiboot2 payload/program/kernel.

Can be transformed to any other tag (sized or unsized/DST) via Tag::cast_tag.

Do not confuse them with the Multiboot2 header tags. They are something different.

Implementations§

source§

impl Tag

source

pub fn typ(&self) -> TagType

Returns the underlying type of the tag.

source

pub fn cast_tag<'a, T: TagTrait + ?Sized + 'a>(&'a self) -> &'a T

Casts the base tag to the specific tag type.

source

pub fn parse_slice_as_string(bytes: &[u8]) -> Result<&str, StringError>

Parses the provided byte sequence as Multiboot string, which maps to a str.
