Build()

std::shared_ptr< ContextVK > impeller::testing::MockVulkanContextBuilder::Build

(

)

Create a Vulkan context with Vulkan functions mocked. The caller is given a chance to tinker on the settings right before a context is created.

Returns

A context if one can be created.

SetPhysicalDeviceFormatPropertiesCallback()

MockVulkanContextBuilder & impeller::testing::MockVulkanContextBuilder::SetPhysicalDeviceFormatPropertiesCallback ( std::function< void(VkPhysicalDevice physicalDevice, VkFormat format, VkFormatProperties *pFormatProperties)>  format_properties_callback )

inline

Set the behavior of vkGetPhysicalDeviceFormatProperties, which needs to respond differently for different formats.

                                      {

SetSettingsCallback()

MockVulkanContextBuilder & impeller::testing::MockVulkanContextBuilder::SetSettingsCallback ( const std::function< void(ContextVK::Settings &)> &  settings_callback )

inline

A callback that allows the modification of the ContextVK::Settings before the context is made.
