* '''Cargo.lock solution:''' How does this solution handle reproducibly determining what crates need to be downloaded from the Cargo.lock file? “Checksum” means it requires you to specify the checksum of all the downloaded dependencies. “Import” means it dynamically imports and parses Cargo.lock from a Nix expression, which means Cargo.lock needs to be present in the same repository as the nix expressions (or IFD must be used). “Codegen” means it generates a .nix file from the Cargo.lock, which is then committed to source control. | * '''Cargo.lock solution:''' How does this solution handle reproducibly determining what crates need to be downloaded from the Cargo.lock file? “Checksum” means it requires you to specify the checksum of all the downloaded dependencies. “Import” means it dynamically imports and parses Cargo.lock from a Nix expression, which means Cargo.lock needs to be present in the same repository as the nix expressions (or IFD must be used). “Codegen” means it generates a .nix file from the Cargo.lock, which is then committed to source control. | ||
* '''Derivations:''' How many derivations does this solution use to compile Rust code? “1” means the project and all its dependencies are compiled in one derivation. “2” means all dependencies are moved into a separate derivation, so the project can be updated independently, but any change to the set of dependencies rebuilds everything. “Many” means each dependency is built in its own derivation, so changes to dependencies only do the minimal amount of rebuilding necessary (and, ideally, different projects can share dependencies, although I haven’t checked if this works in practice). | * '''Derivations:''' How many derivations does this solution use to compile Rust code? “1” means the project and all its dependencies are compiled in one derivation. “2” means all dependencies are moved into a separate derivation, so the project can be updated independently, but any change to the set of dependencies rebuilds everything. “Many” means each dependency is built in its own derivation, so changes to dependencies only do the minimal amount of rebuilding necessary (and, ideally, different projects can share dependencies, although I haven’t checked if this works in practice). | ||
