Struct keos::mm::Page

pub struct Page { /* private fields */ }

A Page representation.

Implementations

impl Page

pub fn new() -> Option<Self>

Allocate a page.

pub fn va(&self) -> Va

Get virtual address of this page.

pub fn pa(&self) -> Pa

Get physical address of this page.

pub fn into_raw(self) -> Pa

Consumes the page, returning a pa of the page.

After calling this function, the caller is responsible for the memory previously managed by the Page. In particular, the caller should properly release the page by calling the Page::from_pa.

pub unsafe fn from_pa(pa: Pa) -> Self

Constructs a page from a pa.

For this to be safe, the pa must have been taken by Page::into_raw.

Safety

This function is unsafe because improper use may lead to memory problems. For example, a double-free may occur if the function is called twice on the same raw pointer.

pub unsafe fn inner(&self) -> &[u8]

Get reference of underlying slice of the Page.

pub unsafe fn inner_mut(&mut self) -> &mut [u8]

Get mutable reference of underlying sliceof the Page.
