From 83291ff51ec85b89bb8aae2c0a260e00ebde7164 Mon Sep 17 00:00:00 2001 From: Florian Klink Date: Mon, 15 Jan 2024 20:13:26 +0200 Subject: refactor(tvix/glue/known_paths): drop some unused stuff This are leftovers from the "reference scanning" approach (which we didn't end up using). We still want a concept of known paths, so we can trace IO into storepaths back to the build recipe that'll produce it, so let's keep the rest of this struct around.
