Expand description
This module holds abstractions that enable tracking the areas dirtied by writes of a specified
length to a given offset. In particular, this is used to track write accesses within a
GuestMemoryRegion
object, and the resulting bitmaps can then be aggregated to build the
global view for an entire GuestMemory
object.
Structs§
AtomicBitmap
implements a simple bit map on the page level with test and set operations. It is page-size aware, so it converts addresses to page numbers before setting or clearing the bits.
Traits§
- Common bitmap operations. Using Higher-Rank Trait Bounds (HRTBs) to effectively define an associated type that has a lifetime parameter, without tagging the
Bitmap
trait with a lifetime as well. - Trait used to represent that a
BitmapSlice
is aBitmap
itself, but also satisfies the restriction that slices created from it have the same type asSelf
. - Trait implemented by types that support creating
BitmapSlice
objects.
Type Aliases§
- A
BitmapSlice
implementation that uses anArc
handle to aBitmap
object. - Helper type alias for referring to the
BitmapSlice
concrete type associated with an objectB: WithBitmapSlice<'a>
. - Helper type alias for referring to the
BitmapSlice
concrete type associated with the memory regions of an objectM: GuestMemory
. - A
BitmapSlice
implementation that wraps a reference to aBitmap
object.
