Struct AddressHeaderTag

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

Binary address information for non-ELF images.

This information does not need to be provided if the kernel image is in ELF format, but it must be provided if the image is in a.out format or in some other format. Required for legacy boot (BIOS). Determines load addresses.

Implementations

impl AddressHeaderTag

pub const fn new( flags: HeaderTagFlag, header_addr: u32, load_addr: u32, load_end_addr: u32, bss_end_addr: u32, ) -> 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 header_addr(&self) -> u32

Returns the header address.

pub const fn load_addr(&self) -> u32

Returns the load begin address.

pub const fn load_end_addr(&self) -> u32

Returns the load end address.

pub const fn bss_end_addr(&self) -> u32

Returns the bss end address.

Trait Implementations

impl Clone for AddressHeaderTag

fn clone(&self) -> AddressHeaderTag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AddressHeaderTag

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

Formats the value using the given formatter.

impl Hash for AddressHeaderTag

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 AddressHeaderTag

const BASE_SIZE: usize = 24usize

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 = HeaderTagHeader

The associated Header of this tag.

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 AddressHeaderTag

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

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

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

const ID: HeaderTagType = HeaderTagType::Address

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

type IDType = HeaderTagType

The ID type that identifies the tag.

impl Copy for AddressHeaderTag
