Before there was code scattered about (e.g. text hashing module and derivation output computation) constructing store paths from low level building blocks --- there was some duplication and it was easy to make nonsense store paths. Now, we have roughly the same "safe-ish" ways of constructing them as C++ Nix, and only those are exposed: - Make text hashed content-addressed store paths - Make other content-addressed store paths - Make input-addressed fixed output hashes Change-Id: I122a3ee0802b4f45ae386306b95b698991be89c8 Reviewed-on: https://cl.tvl.fyi/c/depot/+/8411 Reviewed-by: flokli <flokli@flokli.de> Tested-by: BuildkiteCI
