Struct 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]) -> Box<Self>

Create a new EFI memory map tag with the given memory descriptors.

pub fn new_from_map( desc_size: u32, desc_version: u32, efi_mmap: &[u8], ) -> Box<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 MaybeDynSized for EFIMemoryMapTag

const BASE_SIZE: usize = 16usize

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(header: &TagHeader) -> 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 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 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

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 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

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 Pointee for EFIMemoryMapTag

where [u8]: Pointee,

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

The metadata type for pointers and references to this type.

impl Tag for EFIMemoryMapTag

const ID: TagType = TagType::EfiMmap

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

type IDType = TagType

The ID type that identifies the tag.
