Graphics.Caramia.Internal.Exception

Documentation

data NoSupport

Thrown when there was a detected attempt to use an OpenGL feature that is not supported by the driver, hardware or platform.

Caramia cannot detect all attempts to use non-supported features.

If the platform supports at least OpenGL 3.3, then this exception is guaranteed to never be thrown.

Exception NoSupport

checkExtension :: MonadIO m => Text -> Bool -> m ()

Checks that extension is available and throw NoSupport with the given extension name if it is not.

checkExtensionM :: MonadIO m => Text -> Bool -> m a -> m a

Same as checkExtension but takes an action to run afterwards, it checks for the extension and then runs the action.

checkOpenGLOrExtensionM :: MonadIO m => OpenGLVersion -> Text -> Bool -> m a -> m a

Checks that OpenGL version is at least given version or that an extension is available.

This is for the common case of checking core OpenGL version and falling back to a core extension.

checkOpenGLM :: MonadIO m => OpenGLVersion -> m a -> m a
