Struct qt_gui::q_opengl_functions::OpenGLFeature

#[repr(transparent)]
pub struct OpenGLFeature(_);

This enum defines OpenGL and OpenGL ES features whose presence may depend on the implementation.

C++ enum: QOpenGLFunctions::OpenGLFeature.

C++ documentation:

This enum defines OpenGL and OpenGL ES features whose presence may depend on the implementation.

The OpenGLFeatures type is a typedef for QFlags<OpenGLFeature>. It stores an OR combination of OpenGLFeature values.
