Move path info caching from BinaryCacheStore to Store Caching path info is generally useful. For instance, it speeds up "nix path-info -rS /run/current-system" (i.e. showing the closure sizes of all paths in the closure of the current system) from 5.6s to 0.15s. This also eliminates some APIs like Store::queryDeriver() and Store::queryReferences().

Remove Store::queryDerivationOutputNames() This function was used in only one place, where it could easily be replaced by readDerivation() since it's not performance-critical.

Add function queryPathFromHashPart() To implement binary caches efficiently, Hydra needs to be able to map the hash part of a store path (e.g. "gbg...zr7") to the full store path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5"). (The binary cache mechanism uses hash parts as a key for looking up store paths to ensure privacy.) However, doing a search in the Nix store for /nix/store/<hash>* is expensive since it requires reading the entire directory. queryPathFromHashPart() prevents this by doing a cheap database lookup.

nix-store -q --roots: Respect the gc-keep-outputs/gc-keep-derivations settings So if a path is not garbage solely because it's reachable from a root due to the gc-keep-outputs or gc-keep-derivations settings, ‘nix-store -q --roots’ now shows that root.

Make the Store API more type-safe Most functions now take a StorePath argument rather than a Path (which is just an alias for std::string). The StorePath constructor ensures that the path is syntactically correct (i.e. it looks like <store-dir>/<base32-hash>-<name>). Similarly, functions like buildPaths() now take a StorePathWithOutputs, rather than abusing Path by adding a '!<outputs>' suffix. Note that the StorePath type is implemented in Rust. This involves some hackery to allow Rust values to be used directly in C++, via a helper type whose destructor calls the Rust type's drop() function. The main issue is the dynamic nature of C++ move semantics: after we have moved a Rust value, we should not call the drop function on the original value. So when we move a value, we set the original value to bitwise zero, and the destructor only calls drop() if the value is not bitwise zero. This should be sufficient for most types. Also lots of minor cleanups to the C++ API to make it more modern (e.g. using std::optional and std::string_view in some places).
