From d38f860c3ef001a456d4d447f89219de5e3c830c Mon Sep 17 00:00:00 2001 From: regnat Date: Wed, 10 Jun 2020 11:20:52 +0200 Subject: Add a way to get all the outputs of a derivation with their label Generalize `queryDerivationOutputNames` and `queryDerivationOutputs` by adding a `queryDerivationOutputMap` that returns the map `outputName=>outputPath` (not that this is not equivalent to merging the results of `queryDerivationOutputs` and `queryDerivationOutputNames` as sets don't preserve the order, so we would end up with an incorrect mapping). squash!
