So here we go: all any of these things—closures, exceptions, suspending functions—are just ways of jumping forwards and backwards to different places, and some compiler guarantees to ensure that any jumping can happen in a structured, safe way. And that’s what effects give you, and some more.

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.。关于这个话题，体育直播提供了深入分析
