Trait Implementations§

source§

impl BusDevice for Pflash

source§

fn device_id(&self) -> DeviceId

Returns a unique id per device type suitable for metrics gathering.
source§

fn debug_label(&self) -> String

Returns a label suitable for debug output.
source§

fn read(&mut self, info: BusAccessInfo, data: &mut [u8])

Reads at offset from this device
source§

fn write(&mut self, info: BusAccessInfo, data: &[u8])

Writes at offset into this device
source§

fn config_register_write( &mut self, reg_idx: usize, offset: u64, data: &[u8] ) -> ConfigWriteResult

Sets a register in the configuration space. Only used by PCI. Read more
source§

fn config_register_read(&self, reg_idx: usize) -> u32

Gets a register from the configuration space. Only used by PCI. Read more
source§

fn init_pci_config_mapping( &mut self, shmem: &SharedMemory, base: usize, len: usize ) -> bool

Provides a memory region to back MMIO access to the configuration space. If the device can keep the memory region up to date, then it should return true, after which no more calls to config_register_read will be made. Otherwise the device should return false. Read more
source§

fn virtual_config_register_write(&mut self, reg_idx: usize, value: u32)

Sets a register in the virtual config space. Only used by PCI. Read more
source§

fn virtual_config_register_read(&self, reg_idx: usize) -> u32

Gets a register from the virtual config space. Only used by PCI. Read more
source§

fn on_sandboxed(&mut self)

Invoked when the device is sandboxed.
source§

fn get_ranges(&self) -> Vec<(BusRange, BusType)>

Gets a list of all ranges registered by this BusDevice.
source§

fn destroy_device(&mut self)

Invoked when the device is destroyed
source§

fn is_bridge(&self) -> Option<u8>

Returns the secondary bus number if this bus device is pci bridge
source§

impl Suspendable for Pflash

source§

fn snapshot(&mut self) -> Result<Value>

Save the device state in an image that can be restored.
source§

fn restore(&mut self, data: Value) -> Result<()>

Load a saved snapshot of an image.
source§

fn sleep(&mut self) -> Result<()>

Stop all threads related to the device. Sleep should be idempotent.
source§

fn wake(&mut self) -> Result<()>

Create/Resume all threads related to the device. Wake should be idempotent.

Blanket Implementations§

source§

impl<T> Any for Twhere T: 'static + ?Sized,

source§

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more
source§

impl<T> Borrow<T> for Twhere T: ?Sized,

source§

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more
source§

impl<T> BorrowMut<T> for Twhere T: ?Sized,

source§

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more
§

impl<T> Downcast for Twhere T: Any,

§

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

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, Global>) -> Rc<dyn Any, Global>

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.
source§

impl<T> From<T> for T

source§

fn from(t: T) -> T

source§

impl<T, U> Into<U> for Twhere U: From<T>,

source§

fn into(self) -> U
