mononix/Mononix/Rust build tools in Nix.md

# Rust
## Tools

I am building this table to evaluate tools from the perspective that I would want to use Nix as a replacement for Make in a monorepo environment. "Monorepo" in this case is a shorthand for "many crates being developed in parallel with the clients that depend upon them."

|                      | Dependency cache strategy           | Cross-compilation | Acceptable for Nixpkgs |
| -------------------- | ----------------------------------- | ----------------- | ---------------------- |
| [[Crane]]            | One derivation for all dependencies |                   |                        |
| [[buildRustPackage]] |                                     |                   |                        |
| [[buildRustCrate]]   |                                     |                   |                        |
| [[cargo2nix]]        |                                     |                   | no                     |
| [[crate2nix]]        |                                     |                   | no                     |
| [[naersk]]           |                                     |                   |                        |

Nothing short of caching each dependency in a separate crate will make a tool acceptable for monorepo development.
