Nix can do it incremental U could split it into multiple derivations which get built into one package For rust there ist the excellent https://crane.dev/index.html https://crane.dev/index.html project Or you can also go to the extreme and do 1:1 source to derivation mapping So for example if ur project has 100 source files it could be built from 100 derivations, the language/CLI tools are flexible enough for that https://discourse.nixos.org/t/distributed-nix-build-split-large-package-into-many-derivations/15979 https://discourse.nixos.org/t/distributed-nix-build-split-la... https://discourse.nixos.org/t/per-file-derivations-with-c/19409 https://discourse.nixos.org/t/per-file-derivations-with-c/19... Don't know tho if there any well working smart nix tools which can make it well working /efficient, in theory it's very possible, just unsure about practicality/overheads
