# We build the alias to sieve tool here, this is a two step process, we first generate
|
|
# a nix expression with the crate2nix tool from nixpkgs that directly calls rustc
|
|
# and thus bypasses cargo. We could also generate this file by hand and version it,
|
|
# but that would need regeneration every time some dependency is updated, so we
|
|
# opt for build time generation. Afterwards we import and evaluate the generated
|
|
# nix expression to build the package. For the explicit solution see:
|
|
# https://nix-community.github.io/crate2nix/00_guides/30_generating/
|
|
# and for the documentation to this one
|
|
# https://nix-community.github.io/crate2nix/00_guides/31_auto_generating/
|
|
# as this module uses idf and forces builds during the evaluation it might
|
|
# have drastic performance implications, see
|
|
# https://nix.dev/manual/nix/2.24/language/import-from-derivation
