In the following commits it will become less prevalent.

2020-06-24Add a way to get all the outputs of a derivation with their labelregnat
Generalize `queryDerivationOutputNames` and `queryDerivationOutputs` by adding a `queryDerivationOutputMap` that returns the map `outputName=>outputPath` (not that this is not equivalent to merging the results of `queryDerivationOutputs` and `queryDerivationOutputNames` as sets don't preserve the order, so we would end up with an incorrect mapping). squash! Add a way to get all the outputs of a derivation with their label Rename StorePathMap to OutputPathMap

2020-06-17Add StorePathCAMap for querySubstitutablePathInfosMatthew Bauer
I’m not 100% sure this is wanted since it kind of makes everything have to know about ca even if they don’t really want to. But it also make things easier in dealing with looking up ca.

2020-06-16StorePath: Rewrite in C++Eelco Dolstra
On nix-env -qa -f '<nixpkgs>', this reduces maximum RSS by 20970 KiB and runtime by 0.8%. This is mostly because we're not parsing the hash part as a hash anymore (just validating that it consists of base-32 characters). Also, replace storePathToHash() by StorePath::hashPart().

Do idiomatic C++ copy and move constructors for a few things, so wrapping structs' defaults can work.

2019-12-10Make the Store API more type-safeEelco Dolstra
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).
