This is used in few enough places to just inline it. It felt a bit alien in the ATerm construction aswell. write.rs now pleasantly only includes tokens that occur in the ATerm representation.

2023-01-23 r/5738 refactor(tvix/derivation): pass fingerprint to build_store_pathFlorian Klink2-66/+51
All of these occurences are actually sha256 digests of some fingerprint - which means there's not a lot of need to do the hashing outside. Instead of passing in a digest, keep the sha256 hasher in the function, and pass in a fingerprint. This makes it much easier to construct fingerprints using format!() in all consumers, because we need don't need to juggle with the hasher anymore.

This allows calling validate() on a derivation that doesn't have its output paths already calculated yet. It allows offloading some of the error checking in builtins.derivation* to be offloaded to that function.

`drv` is an invalid output name too, as this would cause a `builtins.derivation` call to return an attrset with a `drvPath` key (which already exists) and has a different meaning. Also handle errors during store path construction, and return our own error type, instead of the ParseStorePathError.

2023-01-16 r/5666 chore(tvix/derivation): drop TODOs related to stripping outputsFlorian Klink1-2/+0
Different to the go-nix implementation, we don't have a custom "writing mode" where output paths are omitted from output, but we simply run the serialization with these fields unpopulated (during construction). This means, there's no need for a custom writing mode that strips outputs, so we can drop the comments.

2023-01-13 r/5657 refactor(tvix/derivation): use BTreeSet for derivation outputsVincent Ambo4-16/+13
When constructing derivations inside builtins.derivationStrict, we'd have to very frequently check whether certain outputs have already been inserted into the derivation inputs. Using a set type is much easier, especially as this has to be ordered and the source data that is being inserted also comes from a set, which might let us pass this more efficiently in the future. Note that the validate function no longer checks the order of the entries, as that is now guaranteed by the type.

2023-01-04 r/5589 refactor(tvix/derivation): make output hashes an Option<Hash>Florian Klink2-29/+35
This conveys better if an output of a Derivation is fixed-output or not, and provides a Hash struct that can be used to store the algo and digest. In case it's not, this can simply be None. The serde field attributes have been updated to still accept the same JSON. We currently still store the hash algo and digest as strings, mostly because the only thing populating it so far is the example JSONs. We might want to update this, once actual Nix code populates this. While updating write.rs, I pushed some of the Vec<String> to [&str] conversions inline, and made it a Vec<&str>, because it was annoying to juggle with.
