Struct devices::virtio::media::GuestMemoryMapper

source · 
struct GuestMemoryMapper(GuestMemory);
Expand description

Newtype to implement VirtioMediaGuestMemoryMapper on GuestMemory.

Whether to use a direct mapping or to copy the guest data into a shadow buffer is decided by the size of the guest mapping. If it is below MAPPING_THRESHOLD, a shadow buffer is used ; otherwise the area is mapped.

impl VirtioMediaGuestMemoryMapper for GuestMemoryMapper

§

type GuestMemoryMapping = GuestMemoryChunk

Host-side linear mapping of sparse guest memory.
source§

fn new_mapping(&self, sgs: Vec<SgEntry>) -> Result<Self::GuestMemoryMapping>

Maps sgs, which contains a list of guest-physical SG entries into a linear mapping on the host.

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.

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

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