Struct VBEInfoTag

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

This tag contains VBE metadata, VBE controller information returned by the VBE Function 00h and VBE mode information returned by the VBE Function 01h.

Implementations

impl VBEInfoTag

pub fn new( mode: u16, interface_segment: u16, interface_offset: u16, interface_length: u16, control_info: VBEControlInfo, mode_info: VBEModeInfo, ) -> Self

Constructs a new tag.

pub const fn mode(&self) -> u16

Indicates current video mode in the format specified in VBE 3.0.

pub const fn interface_segment(&self) -> u16

Returns the segment of the table of a protected mode interface defined in VBE 2.0+.

If the information for a protected mode interface is not available this field is set to zero.

pub const fn interface_offset(&self) -> u16

Returns the segment offset of the table of a protected mode interface defined in VBE 2.0+.

If the information for a protected mode interface is not available this field is set to zero.

pub const fn interface_length(&self) -> u16

Returns the segment length of the table of a protected mode interface defined in VBE 2.0+.

If the information for a protected mode interface is not available this field is set to zero.

pub const fn control_info(&self) -> VBEControlInfo

Returns VBE controller information returned by the VBE Function 00h.

pub const fn mode_info(&self) -> VBEModeInfo

Returns VBE mode information returned by the VBE Function 01h.

Trait Implementations

impl Clone for VBEInfoTag

fn clone(&self) -> VBEInfoTag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VBEInfoTag

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

Formats the value using the given formatter.

impl Hash for VBEInfoTag

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 VBEInfoTag

const BASE_SIZE: usize = 784usize

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>().

type Header = TagHeader

The associated Header of this tag.

fn dst_len(_: &TagHeader)

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 VBEInfoTag

fn cmp(&self, other: &VBEInfoTag) -> 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 VBEInfoTag

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

fn partial_cmp(&self, other: &VBEInfoTag) -> 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 VBEInfoTag

const ID: TagType = TagType::Vbe

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

type IDType = TagType

The ID type that identifies the tag.
