"In the same vein of my earlier post on [swift2nix]({% link "
"_articles/2020-10-05-swift2nix-run-swift-inside-nix-builds.md %}), I was "

"That `cargo test` part on line 20 is what I have been fighting with every "
"\"\\*2nix\" available for Rust out there. I don't want to bash any of them. "
"All I want is to have full control of what Cargo commands to run, and the "
"\"*2nix\" tool should only setup the environment for me. Let me drive Cargo "
"myself, no need to parameterize how the tool runs it for me, or even "
"replicate its internal behaviour by calling the Rust compiler directly."
msgstr ""
msgid ""
"Sure it doesn't support private registries or Git dependencies, but how much"
" bigger does it has to be to support them? Also, it doesn't support those "
"**yet**, there's no reason it can't be extended. I just haven't needed it "
"yet, so I haven't added. Patches welcome."

"The layout of the `vendor/` directory is more explicit and public then what "
