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 a Bitmap
itself, but also satisfies the
restriction that slices created from it have the same type as Self
.
Trait implemented by types that support creating BitmapSlice
objects.
Type Definitions
A BitmapSlice
implementation that uses an Arc
handle to a Bitmap
object.
Helper type alias for referring to the BitmapSlice
concrete type associated with
an object B: WithBitmapSlice<'a>
.
Helper type alias for referring to the BitmapSlice
concrete type associated with
the memory regions of an object M: GuestMemory
.
A BitmapSlice
implementation that wraps a reference to a Bitmap
object.
