Implementations§

source§

impl ExportedRegion

source

pub fn new( mem: &GuestMemory, iommu: Arc<Mutex<IpcMemoryMapper>>, iova: u64, size: u64 ) -> Result<Self>

Creates a new, fully initialized exported region.

source

fn do_copy<C>( &self, iova: u64, remaining: usize, prot: Protection, copy_fn: C ) -> Result<()>

source

pub fn read_obj_from_addr<T: FromBytes>( &self, mem: &GuestMemory, iova: u64 ) -> Result<T>

Reads an object from the given iova. Fails if the specified iova range does not lie within this region, or if part of the region isn’t readable.

source

pub fn write_obj_at_addr<T: AsBytes>( &self, mem: &GuestMemory, val: T, iova: u64 ) -> Result<()>

Writes an object at a given iova. Fails if the specified iova range does not lie within this region, or if part of the region isn’t writable.

source

pub fn is_valid(&self, mem: &GuestMemory, iova: u64, size: u64) -> bool

Validates that [iova, iova+size) lies within this region, and that the region is valid according to mem.

source

pub fn get_mem_regions(&self) -> SmallVec<[MemRegion; 1]>

Gets the list of guest physical regions for the exported region.

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
