Fields

ty: MemoryType

Type of memory occupying this range.

phys_start: u64

Starting physical address.

virt_start: u64

Starting virtual address.

page_count: u64

Number of 4 KiB pages contained in this range.

att: MemoryAttribute

Trait Implementations

impl Align for MemoryDescriptor

fn alignment() -> usize

Required memory alignment for this type

fn offset_up_to_alignment(val: usize) -> usize

Calculate the offset from val necessary to make it aligned, rounding up. For example, if val is 1 and the alignment is 8, this will return 7. Returns 0 if val == 0.

fn round_up_to_alignment(val: usize) -> usize

Round val up so that it is aligned.

fn align_buf(buf: &mut [u8]) -> Option<&mut [u8]>

Get a subslice of buf where the address of the first element is aligned. Returns None if no element of the buffer is aligned.

fn assert_aligned(storage: &mut [u8])

Assert that some storage is correctly aligned for this type

impl Clone for MemoryDescriptor

fn clone(&self) -> MemoryDescriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryDescriptor

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

Formats the value using the given formatter.

impl Default for MemoryDescriptor

fn default() -> MemoryDescriptor

Returns the “default value” for a type.

impl Copy for MemoryDescriptor
