Struct multiboot2::EFIMemoryMapTag
source · #[repr(C)]pub struct EFIMemoryMapTag { /* private fields */ }
Expand description
EFI memory map tag. The EFIMemoryDesc
follows the EFI specification.
Implementations§
source§impl EFIMemoryMapTag
impl EFIMemoryMapTag
sourcepub fn new(descs: &[EFIMemoryDesc]) -> BoxedDst<Self>
pub fn new(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.
sourcepub fn memory_areas(&self) -> EFIMemoryAreaIter<'_>
pub fn memory_areas(&self) -> EFIMemoryAreaIter<'_>
Return an iterator over ALL marked memory areas.
This differs from MemoryMapTag
as for UEFI, the OS needs some non-
available memory areas for tables and such.

source§fn dst_size(base_tag: &Tag) -> usize
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. Read more
source§fn as_base_tag(&self) -> &Tag
fn as_base_tag(&self) -> &Tag
Returns the tag as the common base tag structure.
source§fn size(&self) -> usize
fn size(&self) -> usize
Returns the total size of the tag. The depends on the
size
field of
the tag.source§fn as_bytes(&self) -> &[u8]
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.source§unsafe fn from_base_tag<'a>(tag: &Tag) -> &'a Self
unsafe fn from_base_tag<'a>(tag: &Tag) -> &'a 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. Read more
