诺基亚专业拍摄打开专业模式，手动调节快门、ISO、白平衡、对焦，再同时保存 DNG 和 JPEG。这不是什么营销噱头，而是一套真正为摄影爱好者准备的工具链。在今天这个「一键出片」的时代，这种需要你亲自参与每一步的拍摄过程，反而显得格外迷人。

Most of the performance gain comes from replacing multiple nix CLI invocations with a C FFI backend built on nix-bindings-rust. Instead of spawning five or more separate Nix processes per command, devenv 2.0 calls the Nix evaluator and store directly through the C API, evaluating one attribute at a time. This also gives us better error messages and real time progress in the TUI. We currently carry patches against Nix to extend the C FFI interface, but these are fully upstreamable and we plan to contribute them back. Thanks to Robert Hensing for creating nix-bindings-rust and making this possible.
