Struct multiboot2::RsdpV2Tag

#[repr(C)]
pub struct RsdpV2Tag { /* private fields */ }

This tag contains a copy of RSDP as defined per ACPI 2.0 or later specification.

Implementations

impl RsdpV2Tag

pub fn new( signature: [u8; 8], checksum: u8, oem_id: [u8; 6], revision: u8, rsdt_address: u32, length: u32, xsdt_address: u64, ext_checksum: u8, ) -> Self

pub fn signature(&self) -> Result<&str, Utf8Error>

The “RSD PTR “ marker signature.

This is originally a 8-byte C string (not null terminated!) that must contain “RSD PTR “.

pub fn checksum_is_valid(&self) -> bool

Validation of the RSDPv2 extended checksum

pub fn oem_id(&self) -> Result<&str, Utf8Error>

An OEM-supplied string that identifies the OEM.

pub fn revision(&self) -> u8

The revision of the ACPI.

pub fn xsdt_address(&self) -> usize

Physical address of the XSDT table.

On x86, this is truncated from 64-bit to 32-bit.

pub fn ext_checksum(&self) -> u8

This field is used to calculate the checksum of the entire table, including both checksum fields.

Trait Implementations

impl Clone for RsdpV2Tag

fn clone(&self) -> RsdpV2Tag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RsdpV2Tag

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

Formats the value using the given formatter.

impl Hash for RsdpV2Tag

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 RsdpV2Tag

fn cmp(&self, other: &RsdpV2Tag) -> 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 RsdpV2Tag

fn eq(&self, other: &RsdpV2Tag) -> 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 RsdpV2Tag

fn partial_cmp(&self, other: &RsdpV2Tag) -> 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 RsdpV2Tag

const ID: TagType = TagType::AcpiV2

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.
