v0.10.0

0.10.0 - 2022-12-01

Added

• A new installation mode has been defined which symlinks identical cargo
  artifacts against previously generated ones. This allows for linear space
  usage in the Nix store across many chained derivations (as opposed to using a
  zstd compressed tarball which uses quadratic space across many chained
  derivations).
• mkDummySrc optionally accepts a dummyrs argument which allows for
  customizing the contents of the dummy Rust files that will be generated.

Changed

• Breaking: all cargo-based derivations will now default to using symlinking
  their installed artifacts together instead of using zstd compressed tarballs.
  To get the old behavior back, set installCargoArtifactsMode = "use-zstd"; in
  the derivation.
  • Note that buildPackage will continue to use zstd compressed tarballs while
    building dependencies (unless either of cargoArtifacts or
    installCargoArtifactsMode is defined, in which case they will be honored)
• Breaking: the format for defining crate registries has been changed: each
  registry URL should map to a set containing a downloadUrl attribute. This
  set may also define fetchurlExtraArgs (another set) which will be forwarded
  to the fetchurl invocations for crates for that registry.
• Breaking (technically): buildDepsOnly will now only default to running
  cargo check with the --all-targets flag only if doCheck = true; is set on
  the derivation (otherwise the flag is omitted). To get the previous behavior
  back simply set cargoCheckExtraArgs = "--all-targets";.
• registryFromGitIndex now uses shallow checkouts for better performance
• registryFromDownloadUrl and registryFromGitIndex now allow specifying
  fetchurlExtraArgs which will be forwarded to the fetchurl invocations for
  crates for that registry

Fixed

• Unpacking a git repository now ignores duplicate crates to match cargo's
  behavior
• Sped up stripping references to source files
• Dummy sources now import the core crate more robustly (playing more nicely
  with cargo-hakari)
• Building a crate's dependencies automatically works for uefi targets
