2024-03-03 r/7634 feat(tvix/nix-compat): add HashMode and CAHash::mode()Florian Klink1-0/+16
This allows peeking at the mode without matching on all enum kinds of CAHash directly.

2024-03-03 r/7633 fix(tvix/nix-compat): Make CAHash deserialize more formatsBrian Olsen1-66/+180
Currently CAHash only deserializes the hash in hex code while the serializer outputs a nixbase32 hash. This means that you can't currently deserialize what has been serialized. This change makes deserialize support any digest format (so hex, nixbase32 and base64) as well as flattens the deserialize code and error handling. It also implements serde methods of HashAlgo directly using Display and TryFrom implementations because otherwise these would get serialized as eg. Sha256 instead of sha256 which also broke CAHash serialize/deserialize.

2024-03-03 r/7632 refactor(tvix/nix-compat): rename NixHash::{digest,hash}Florian Klink1-1/+1
This doesn't return the digest, but the internal NixHash. To get the digest, you use `ca_hash.hash().digest_as_bytes()` (as done in tvix/nix-compat/src/derivation/write.rs).

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.
