Struct multiboot2::EFIMemoryMapTag

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

EFI memory map tag. The embedded EFIMemoryDescs follows the EFI specification.

Implementations

impl EFIMemoryMapTag

pub fn new_from_descs(descs: &[EFIMemoryDesc]) -> BoxedDst<Self>

Create a new EFI memory map tag with the given memory descriptors. Version and size can’t be set because you’re passing a slice of EFIMemoryDescs, not the ones you might have gotten from the firmware.

pub fn new_from_map( desc_size: u32, desc_version: u32, efi_mmap: &[u8], ) -> BoxedDst<Self>

Create a new EFI memory map tag from the given EFI memory map.

pub fn memory_areas(&self) -> EFIMemoryAreaIter<'_>

Returns an iterator over the provided memory areas.

Usually, this should already reflect the memory consumed by the code running this.

Trait Implementations

impl Debug for EFIMemoryMapTag

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

Formats the value using the given formatter.

impl Hash for EFIMemoryMapTag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

impl Ord for EFIMemoryMapTag

fn cmp(&self, other: &EFIMemoryMapTag) -> Ordering

This method returns an [Ordering] between self and other.

impl PartialEq for EFIMemoryMapTag

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

fn partial_cmp(&self, other: &EFIMemoryMapTag) -> 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 Pointee for EFIMemoryMapTag

where [u8]: Pointee,

type Metadata = <[u8] as Pointee>::Metadata

The type for metadata in pointers and references to Self.

impl TagTrait for EFIMemoryMapTag

const ID: TagType = TagType::EfiMmap

The numeric ID of this tag.

fn dst_size(base_tag: &Tag) -> usize

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.
