Struct Multiboot2BasicHeader

#[repr(C, align(8))]
pub struct Multiboot2BasicHeader { /* private fields */ }

The “basic” Multiboot2 header. This means only the properties, that are known during compile time. All other information are derived during runtime from the size property.

Implementations

impl Multiboot2BasicHeader

pub const fn verify_checksum(&self) -> bool

Verifies that 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.

Trait Implementations

impl Clone for Multiboot2BasicHeader

fn clone(&self) -> Multiboot2BasicHeader

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Multiboot2BasicHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Multiboot2BasicHeader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Header for Multiboot2BasicHeader

fn payload_len(&self) -> usize

Returns the length of the payload, i.e., the bytes that are additional to the header. The value is measured in bytes.

fn set_size(&mut self, total_size: usize)

Updates the header with the given total_size.

fn total_size(&self) -> usize

Returns the total size of the struct, thus the size of the header itself plus Header::payload_len.

impl Ord for Multiboot2BasicHeader

fn cmp(&self, other: &Multiboot2BasicHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Multiboot2BasicHeader

fn eq(&self, other: &Multiboot2BasicHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Multiboot2BasicHeader

fn partial_cmp(&self, other: &Multiboot2BasicHeader) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
