2023-11-22 r/7045 refactor(tvix/nix-compat): cleanup parse_{ca,hash} and fmt structsFlorian Klink1-6/+42
These were used to format to and parse from strings. Move this to the CAHash and NixHash structs directly, and be explicit in the name about which encoding for digests is used. For output path calculation, nix encodes the nixpaths in hex, but for writing out NARInfos, it's using nixbase32.

2023-10-23 r/6871 refactor(tvix/nix-compat): rename NixHashWithMode -> CAHashFlorian Klink1-0/+177
This specific struct is only used to represent content-addressed paths (in case a Derivation has a fixed-output hash, for example). Rename `Output`'s `hash_with_mode` to `ca_hash`. We now also include `CAHash::Text`, and update the `validate` function of the `Output` struct to reject text hashes there. This allows cleaning up the various output path calculation functions inside nix-compat/src/store_path/utils.rs, as they can now match on the type. `make_type` is renamed to `make_references_string`, `build_regular_ca_path` is renamed to `build_ca_path`, and `build_text_path` has a disclaimer added, because you might not actually want to use it.
