Struct MemoryRegion 

pub struct MemoryRegion(/* private fields */);

A range of virtual addresses which may be mapped in a page table.

Implementations

impl MemoryRegion

pub const fn new(start: usize, end: usize) -> MemoryRegion

Constructs a new MemoryRegion for the given range of virtual addresses.

The start is inclusive and the end is exclusive. Both will be aligned to the PAGE_SIZE, with the start being rounded down and the end being rounded up.

pub const fn start(&self) -> VirtualAddress

Returns the first virtual address of the memory range.

pub const fn end(&self) -> VirtualAddress

Returns the first virtual address after the memory range.

pub const fn len(&self) -> usize

Returns the length of the memory region in bytes.

pub const fn is_empty(&self) -> bool

Returns whether the memory region contains exactly 0 bytes.

Trait Implementations

impl Clone for MemoryRegion

fn clone(&self) -> MemoryRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryRegion

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

Formats the value using the given formatter.

impl Display for MemoryRegion

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

Formats the value using the given formatter.

impl From<Range<VirtualAddress>> for MemoryRegion

fn from(range: Range<VirtualAddress>) -> Self

Converts to this type from the input type.

impl PartialEq for MemoryRegion

fn eq(&self, other: &MemoryRegion) -> 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.
