John Ericson	f4ab297b31	Ensure all headers have #pragma once and are in API docs ... `///@file` makes them show up in the internal API dos. A tiny few were missing `#pragma once`.	2023-03-31 23:19:44 -04:00
John Ericson	abd5e7dec0	Extend internal API docs, part 2 ... Picking up from #8111. Co-authored-by: Eelco Dolstra <edolstra@gmail.com>	2023-03-31 23:01:40 -04:00
John Ericson	c998e0172f	Move value-only methods to InstallableValue ... These methods would previously fail on the other `Installable`s, so moving them to this class is more correct as to where they actually work. Additionally, a `InstallableValueCommand` is created to make it easier (or rather no worse than before) to write commands that just work on `InstallableValue`s. Besides being a cleanup to avoid failing default methods, this gets us closer to https://github.com/NixOS/rfcs/pull/134.	2023-03-16 20:06:46 -04:00
