Struct MockDeviceInfo

pub struct MockDeviceInfo<T: TestLayerMock> {
    pub mock_hooks: Mutex<MockDeviceHooks>,
    /* private fields */
}

Available on crate feature _test only.

A mock struct that implements the DeviceInfo trait.

The T type parameter is a TestLayerMock type that provides the mock of DeviceInfo::hooked_commands.

Fields

mock_hooks: Mutex<MockDeviceHooks>

The mock of the DeviceHooks.

Implementations

impl<T: TestLayerMock> MockDeviceInfo<T>

pub fn with_mock_drop(&self, f: impl FnOnce(&mut MockDrop))

Mock the drop behavior.

The expectations can be set through the f argument. If this method is never called, the struct will be dropped as if the drop is not mocked, i.e. won’t check how drop is called.

Trait Implementations

impl<T: Default + TestLayerMock> Default for MockDeviceInfo<T>

fn default() -> MockDeviceInfo<T>

Returns the “default value” for a type.

impl<T: TestLayerMock> DeviceInfo for MockDeviceInfo<T>

type HooksType = MockDeviceHooks

The underlying DeviceHooks type that implements the core logic to intercept Vulkan device functions.

type HooksRefType<'a> = MutexGuard<'a, MockDeviceHooks>

A type that can be dereferencing to DeviceInfo::HooksType. Usually just &DeviceInfo::HooksType.

fn hooked_commands() -> &'static [LayerVulkanCommand]

Returns a slice of Vulkan device functions that the layer implementation needs to intercept.

fn hooks(&self) -> Self::HooksRefType<'_>

Returns the reference of the DeviceInfo::HooksType.
