Struct keos::addressing::Va

pub struct Va(_);

Virtual address

Implementations

impl Va

pub const fn new(addr: usize) -> Option<Va>

Create a new virtual address with a check.

pub const unsafe fn into_usize(self) -> usize

Cast into usize.

pub const fn into_pa(self) -> Pa

Cast into physical address.

pub unsafe fn as_ref<'a, T>(&self) -> Option<&'a T>

Get reference of T underlying the Va.

Safety

When calling this method, you have to ensure that either the pointer is null or all of the following is true:

• The pointer must be properly aligned.

• It must be “dereferenceable” in the sense defined in the module documentation.

• The pointer must point to an initialized instance of T.

This applies even if the result of this method is unused!

pub unsafe fn as_mut<'a, T>(&self) -> Option<&'a mut T>

Get mutable reference of T underlying the Va.

Safety

When calling this method, you have to ensure that either the pointer is null or all of the following is true:

• The pointer must be properly aligned.

impl Ord for Va

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

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

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.
