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.
