enable_playground

bool impeller::PlaygroundSwitches::enable_playground = false

Definition at line 16 of file switches.h.

enable_vulkan_validation

bool impeller::PlaygroundSwitches::enable_vulkan_validation = false

Definition at line 21 of file switches.h.

enable_wide_gamut

bool impeller::PlaygroundSwitches::enable_wide_gamut = false

Definition at line 35 of file switches.h.

timeout

std::optional<std::chrono::milliseconds> impeller::PlaygroundSwitches::timeout

Definition at line 20 of file switches.h.

use_angle

bool impeller::PlaygroundSwitches::use_angle = false

Attempt to use Angle on the system instead of the available OpenGL ES implementation. This is on-by-default on macOS due to the broken-ness in the deprecated OpenGL implementation. On other platforms, it this opt-in via the flag with the system OpenGL ES implementation used by fault.

Definition at line 33 of file switches.h.

use_swiftshader

bool impeller::PlaygroundSwitches::use_swiftshader = false

Seek a SwiftShader library in known locations and use it when running Vulkan. It is a fatal error to provide this option and not have the test find a SwiftShader implementation.
