Variants

OpenGpioFileFailed(Error)

In order to function, the file /dev/gpiomem needs to be opened. This error means that that did not work. The most likely reason is that the program is not run as root / has access to the file or that the program has been run on a device that is not a raspberry pi.

CreateMmapError(Error)

An Error happened in trying to map the already opened File to memory. See contained io::Error for more information.
