== OpenSessionForDev ==
Takes a raw [[#GpioPadDescriptor]] and returns a [[#IPadSession]] session for it.

== OpenSession ==
Same thing as [[#OpenSessionForDev]] except it takes a '''GpioPadName''' which is then converted to a [[#GpioPadDescriptor]]. Returns an [[#IPadSession]] session.

== OpenSessionForTest ==
Same as [[#OpenSession]] but panics on failure.

== OpenSession2 ==
Same as [[#OpenSession]] but takes a '''DeviceCode''' instead of a '''GpioPadName'''.

== IPadSession ==
This is "nn::gpio::IPadSession".
