A single derived path that is built from a derivation
Built derived paths are pair of a derivation and an output name. They are evaluated by building the derivation, and then taking the resulting output path of the given output name.
const StorePath & nix::SingleDerivedPath::Built::getBaseStorePath | ( | ) | const |
Get the store path this is ultimately derived from (by realising and projecting outputs).
Note that this is not a property of the store object being referred to, but just of this path — how we happened to be referring to that store object. In other words, this means this function breaks "referential transparency". It should therefore be used only with great care.

The caller splits on the separator, so it works for both variants.

std::string nix::SingleDerivedPath::Built::to_string | ( | const StoreDirConfig & | store | ) | const |
Uses ^

std::string nix::SingleDerivedPath::Built::to_string_legacy | ( | const StoreDirConfig & | store | ) | const |
Uses !
