It turns out that `cargo`, with respect to registry dependencies, was ignoring the package versions locked in `Cargo.lock` because we changed the registry index URL. Therefore, every time `rustRegistry` would be updated, we'd always try to use the latest version available for every dependency and as a result the deps' SHA256 hashes would almost always have to be changed. To fix this, now we do a string substitution in `Cargo.lock` of the `crates.io` registry URL with our URL. This should be safe because our registry is just a copy of the `crates.io` registry at a certain point in time. Since now we don't always use the latest version of every dependency, the build of `cargo` actually started to fail because two of the dependencies specified in its `Cargo.lock` file have build failures. To fix the latter problem, I've added a `cargoUpdateHook` variable that gets ran both when fetching dependencies and just before building the program. The purpose of `cargoUpdateHook` is to do any ad-hoc updating of dependencies necessary to get the package to build. The use of the '--precise' flag is needed so that cargo doesn't try to fetch an even newer version whenever `rustRegistry` is updated (and therefore have to change depsSha256 as a consequence). |
