Expand description
A wrapper over an ArcSwap<GuestMemory> struct to support RCU-style mutability.
With the backend-atomic feature enabled, simply replacing GuestMemoryMmap
with GuestMemoryAtomic<GuestMemoryMmap> will enable support for mutable memory maps.
To support mutable memory maps, devices will also need to use
GuestAddressSpace::memory() to gain temporary access to guest memory.
Structs
A fast implementation of a mutable collection of memory regions.
An RAII implementation of a “scoped lock” for
GuestMemoryAtomic. When
this structure is dropped (falls out of scope) the lock will be unlocked,
possibly after updating the memory map represented by the
GuestMemoryAtomic that created the guard.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.
