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

Fields

mode: u16

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

interface_segment: u16

Contain 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.

interface_offset: u16

Contain 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.

interface_length: u16

Contain 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.

control_info: VBEControlInfo

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

mode_info: VBEModeInfo

Contains 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 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for VBEInfoTag

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

This method tests for self and other values to be equal, and is used by ==.

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

This method 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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TagTrait for VBEInfoTag

const ID: TagType = TagType::Vbe

The numeric ID of this tag.

fn dst_size(_base_tag: &Tag)

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 as_base_tag(&self) -> &Tag

Returns the tag as the common base tag structure.

fn size(&self) -> usize

Returns the total size of the tag. The depends on the size field of the tag.

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

Returns a slice to the underlying bytes of the tag. This includes all bytes, also for tags that are DSTs. The slice length depends on the size field of the tag.

unsafe fn from_base_tag(tag: &Tag) -> &Self

Creates a reference to a (dynamically sized) tag type in a safe way. DST tags need to implement a proper Self::dst_size implementation.
