pub fn driver_load_error() -> Option<&'static DriverLoadError>Expand description
Returns the cached DriverLoadError from the first driver-load attempt,
if the driver failed to load.
This lets callers programmatically inspect why the driver is unavailable
(which library was missing, which symbol failed to resolve, or the cuInit
error code) rather than only seeing the coarse
CudaError::NotInitialized returned by try_driver. Returns None if
the driver loaded successfully or has not been probed yet.
