impl MappedRegion for RutabagaMemoryRegion

fn as_ptr(&self) -> *mut u8

Returns a pointer to the beginning of the memory region. Should only be used for passing this region to ioctls for setting guest memory.

fn size(&self) -> usize

Returns the size of the memory region in bytes.

fn add_fd_mapping( &mut self, _offset: usize, _size: usize, _fd: &dyn AsRawDescriptor, _fd_offset: u64, _prot: Protection, ) -> Result<(), Error>

Maps size bytes starting at fd_offset bytes from within the given fd at offset bytes from the start of the region with prot protections. offset must be page aligned.

fn remove_mapping(&mut self, _offset: usize, _size: usize) -> Result<(), Error>

Remove size-byte mapping starting at offset.
