Implementations§

Source§

impl ContigPages

Source

pub fn new(size: usize) -> Option<Self>

Allocate a page.

Source

pub fn new_with_align(size: usize, align: usize) -> Option<Self>

Allocate a page with align

Source

pub fn kva(&self) -> Kva

Get virtual address of this page.

Source

pub unsafe fn from_va(kva: Kva, size: usize) -> Self

Constructs a page from a kva.

§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.

Source

pub fn split(self) -> Vec<Page>

Split the ContigPages into multiple pages.
