Build Rust in Nix

Examples of building rust projects using Nix

Tools

• rustPlatform.buildRustPackage: ./buildrustpackage-example

• crate2nix: ./crate2nix-example

Notes

• I’m including the Tokio dependency as a git repo. It is absolutely unneeded but it forces to show how to deal with outputHashes for buildRustPackage.

• I explicitly set lld as a linker since I’m not sure if it’s the default for the stable channel. It is provided by pkgs.llvmPackages.ld, which is a wrapper around lld.
  objdump -j .comment -s /path/to/target/debug/buildrustpackage-example will show Linker: LLD
