Struct vm_memory::atomic::GuestMemoryLoadGuard

source · [−]

pub struct GuestMemoryLoadGuard<M: GuestMemory> { /* private fields */ }

Expand description

A guard that provides temporary access to a GuestMemoryAtomic. This object is returned from the memory() method. It dereference to a snapshot of the GuestMemory, so it can be used transparently to access memory.

Implementations

impl<M: GuestMemory> GuestMemoryLoadGuard<M>

pub fn into_inner(self) -> Arc<M>

Make a clone of the held pointer and returns it. This is more expensive than just using the snapshot, but it allows to hold on to the snapshot outside the scope of the guard. It also allows writers to proceed, so it is recommended if the reference must be held for a long time (including for caching purposes).
