Expand description

Specifies the tolerance of the OpenGL Context to faults. If you accept raw OpenGL commands and/or raw shader code from an untrusted source, you should definitely care about this.

Variants

NotRobust

Not everything is checked. Your application can crash if you do something wrong with your shaders.

NoError

The driver doesn’t check anything. This option is very dangerous. Please know what you’re doing before using it. See the GL_KHR_no_error extension.

Since this option is purely an optimization, no error will be returned if the backend doesn’t support it. Instead it will automatically fall back to NotRobust.

RobustNoResetNotification

Everything is checked to avoid any crash. The driver will attempt to avoid any problem, but if a problem occurs the behavior is implementation-defined. You are just guaranteed not to get a crash.

TryRobustNoResetNotification

Same as RobustNoResetNotification but the context creation doesn’t fail if it’s not supported.

RobustLoseContextOnReset

Everything is checked to avoid any crash. If a problem occurs, the context will enter a “context lost” state. It must then be recreated. For the moment, glutin doesn’t provide a way to recreate a context with the same window :-/

TryRobustLoseContextOnReset

Same as RobustLoseContextOnReset but the context creation doesn’t fail if it’s not supported.
