Struct MockDevice

pub struct MockDevice {
    suspendable_switch: bool,
}

A mock device, for unit-tests.

Fields

suspendable_switch: bool

Implementations

impl MockDevice

pub fn new() -> Self

Create a basic mock device with methods that succeed but do nothing.

pub fn toggle_suspendable_switch(&mut self)

Changes the state of the device in a way that affects its snapshots.

Trait Implementations

impl BusDevice for MockDevice

fn device_id(&self) -> DeviceId

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

fn debug_label(&self) -> String

Returns a label suitable for debug output.

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

Performs a read access to this device, based on info.

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

Performs a write access to this device, based on info.

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.

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

Gets a register from the configuration space. Only used by PCI.

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.

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

Sets a register in the virtual config space. Only used by PCI.

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

Gets a register from the virtual config space. Only used by PCI.

fn on_sandboxed(&mut self)

Invoked when the device is sandboxed.

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

Gets a list of all ranges registered by this BusDevice.

fn destroy_device(&mut self)

Invoked when the device is destroyed

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

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

impl Clone for MockDevice

fn clone(&self) -> MockDevice

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MockDevice

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MockDevice

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MockDevice

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MockDevice

fn eq(&self, other: &MockDevice) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MockDevice

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Suspendable for MockDevice

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

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

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

Load a saved snapshot of an image.

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

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

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

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

impl Eq for MockDevice
