Eelco Dolstra	bbe97dff8b	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).	2019-12-10 22:06:05 +01:00

Eelco Dolstra	d567baabbd	* Export the nix-env derivation name parsing and version comparison ... logic through the `parseDrvName' and `compareVersions' primops. This will allow expressions to easily check whether some dependency is a specific needed version or falls in some version range. See tests/lang/eval-okay-versions.nix for examples.	2008-07-01 10:10:32 +00:00
