Struct multiboot2_header::ConsoleHeaderTag

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

Tells that a console must be available in MBI. Only relevant for legacy BIOS.

Implementations

impl ConsoleHeaderTag

pub const fn new( flags: HeaderTagFlag, console_flags: ConsoleHeaderTagFlags, ) -> Self

Constructs a new tag.

pub const fn typ(&self) -> HeaderTagType

Returns the HeaderTagType.

pub const fn flags(&self) -> HeaderTagFlag

Returns the HeaderTagFlags.

pub const fn size(&self) -> u32

Returns the size.

pub const fn console_flags(&self) -> ConsoleHeaderTagFlags

Returns the ConsoleHeaderTagFlags.

Trait Implementations

impl Clone for ConsoleHeaderTag

fn clone(&self) -> ConsoleHeaderTag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConsoleHeaderTag

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

Formats the value using the given formatter.

impl Hash for ConsoleHeaderTag

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 MaybeDynSized for ConsoleHeaderTag

type Header = HeaderTagHeader

The associated Header of this tag.

const BASE_SIZE: usize = 12usize

The true base size of the struct without any implicit or additional padding. Note that size_of::<T>() isn’t sufficient, as for example the type could have three u32 fields, which would add an implicit u32 padding. However, this constant must always fulfill BASE_SIZE >= size_of::<Self::Header>().

fn dst_len(_header: &Self::Header) -> Self::Metadata

Returns the amount of items in the dynamically sized portion of the DST. Note that this is not the amount of bytes. So if the dynamically sized portion is 16 bytes in size and each element is 4 bytes big, then this function must return 4.

fn header(&self) -> &Self::Header

Returns the corresponding Header.

fn payload(&self) -> &[u8]

Returns the payload, i.e., all memory that is not occupied by the Header of the type.

fn as_bytes(&self) -> BytesRef<'_, Self::Header>

Returns the whole allocated bytes for this structure encapsulated in BytesRef. This includes padding bytes. To only get the “true” tag data, read the tag size from Self::header and create a sub slice.

fn as_ptr(&self) -> *const Self::Header

Returns a pointer to this structure.

impl Ord for ConsoleHeaderTag

fn cmp(&self, other: &ConsoleHeaderTag) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ConsoleHeaderTag

fn eq(&self, other: &ConsoleHeaderTag) -> 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 ConsoleHeaderTag

fn partial_cmp(&self, other: &ConsoleHeaderTag) -> 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.

impl Tag for ConsoleHeaderTag

type IDType = HeaderTagType

The ID type that identifies the tag.

const ID: HeaderTagType = HeaderTagType::ConsoleFlags

The ID of this tag. This should be unique across all implementors.
