Detailed Description

template<typename T, typename E>
struct nix::EvalPaths::PathResult< T, E >

findFile wants to throw a debuggable error when the requested file is not found, but it can't invoke the debugger itself because it's async code. This wraps the result-or-error to allow it regardless. This happens for copyPathToStore as well, with another error type.
