Defines the interface for snapshotting memory.

Required Methods

fn describe(&self) -> GuestMemoryState

Describes GuestMemoryMmap through a GuestMemoryState struct.

fn mark_dirty(&self, addr: GuestAddress, len: usize)

Mark memory range as dirty

fn dump<T: WriteVolatile + Seek>( &self, writer: &mut T, ) -> Result<(), MemoryError>

Dumps all contents of GuestMemoryMmap to a writer.

fn dump_dirty<T: WriteVolatile + Seek>( &self, writer: &mut T, dirty_bitmap: &DirtyBitmap, ) -> Result<(), MemoryError>

Dumps all pages of GuestMemoryMmap present in dirty_bitmap to a writer.

fn reset_dirty(&self)

Resets all the memory region bitmaps

fn store_dirty_bitmap(&self, dirty_bitmap: &DirtyBitmap, page_size: usize)

Store the dirty bitmap in internal store

fn try_for_each_region_in_range<F>( &self, addr: GuestAddress, range_len: usize, f: F, ) -> Result<(), GuestMemoryError>

where F: FnMut(&GuestRegionMmapExt, MemoryRegionAddress, usize) -> Result<(), GuestMemoryError>,

Apply a function to each region in a memory range

fn discard_range( &self, addr: GuestAddress, range_len: usize, ) -> Result<(), GuestMemoryError>

Discards a memory range, freeing up memory pages

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
