Struct Page

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

A page of memory

This represents a single page of memory. When accessing memory, all the memory in the page is paged in and then accessible for the rest of the segment, at which point it is paged out.

Implementations

impl Page

pub fn digest(&self) -> Digest

Produce the digest of this page

Hashes the data in this page to produce a digest wh∑ich can be used for verifying memory integrity.

pub fn load(&self, addr: WordAddr) -> u32

Read a word from a page

Loads the data at addr from this page. This only looks at the subaddress, and does not check if the address belongs to this page. Thus, if you pass a WordAddr belonging to a different page, Page::load will load from the address in this page with the same WordAddr::page_subaddr.

pub fn store(&mut self, addr: WordAddr, word: u32)

Store a word to this page

Stores the data word to the address addr in this page. This only looks at the subaddress, and does not check if the address belongs to this page. Thus, if you pass a WordAddr belonging to a different page, Page::store will store to the address in this page with the same WordAddr::page_subaddr.

pub fn data(&self) -> &Vec<u8>

Get a shared reference to the underlying data in the page
