Struct Snapshot 

pub struct Snapshot { /* private fields */ }

A snapshot of sandbox state that can be used to restore it later. A wrapper around a SharedMemory reference and a snapshot of the memory therein

Trait Implementations

impl AsRef<Snapshot> for Snapshot

fn as_ref(&self) -> &Snapshot

Converts this type into a shared reference of the (usually inferred) input type.

impl PartialEq for Snapshot

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

impl TableReadOps for Snapshot

type TableAddr = u64

The type of table addresses

fn entry_addr(addr: u64, offset: u64) -> u64

Offset the table address by the given offset in bytes.

unsafe fn read_entry(&self, addr: u64) -> u64

Read a u64 from the given address, used to read existing page table entries

fn to_phys(addr: u64) -> u64

Convert an abstract table address to a concrete physical address (u64) which can be e.g. written into a page table entry

fn from_phys(addr: u64) -> u64

Convert a concrete physical address (u64) which may have been e.g. read from a page table entry back into an abstract table address

fn root_table(&self) -> u64

Return the address of the root page table
