[Question] Missing files from build scripts when running crates_vendor

[dk333333]

Hi, I'm playing around with rules_rust release 0.17 in an existing large monorepo targeting linux.

I had to add crate_features = ["force_unix_path_separator"], to .../rules_rust/crate_universe/3rdparty/crates/BUILD.typenum-1.16.0.bazel due to missing an env var (I don't think folks would like to modify env vars in our builds):

--> external/cui__typenum-1.16.0/src/lib.rs:80:5
   |
80 |     include!(env!("TYPENUM_BUILD_OP"));
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |

This seems to be an autogenerated file, is there a way to set this create feature upstream?

With that resolved, I am now running into issues with missing .rs files that are generated in build scripts, for example:

error: couldn't read /b/f/w/bazel-out/k8-opt-exec-EA861D4F/bin/external/cui__unicode-linebreak-0.1.4/unicode-linebreak_build_script.out_dir/tables.rs: No such file or directory (os error 2)
  --> external/cui__unicode-linebreak-0.1.4/src/lib.rs:31:1
   |
31 | include!(concat!(env!("OUT_DIR"), "/tables.rs"));
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
   = note: this error originates in the macro `include` (in Nightly builds, run with -Z macro-backtrace for more info)

error: aborting due to previous error

and

error: couldn't read /b/f/w/bazel-out/k8-opt-exec-EA861D4F/bin/external/cui__typenum-1.16.0/typenum_build_script.out_dir/op.rs: No such file or directory (os error 2)
  --> external/cui__typenum-1.16.0/src/lib.rs:72:5
   |
72 |     include!(concat!(env!("OUT_DIR"), "/op.rs"));
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |

any ideas how to debug this? The bazel-out directory seems reasonable?

load("@rules_rust//crate_universe:defs.bzl", "crate", "crates_vendor")

crates_vendor(
    name = "crates_vendor",
    mode = "remote",
    tags = ["manual"],
    vendor_path = "crates",
)

in workspace:

load("@rules_rust//rust:repositories.bzl", "rules_rust_dependencies", "rust_register_toolchains")

rules_rust_dependencies()

rust_register_toolchains(
    edition = "2021",
    extra_target_triples = [],
    urls = [".../static.rust-lang.org/dist/{}.tar.gz"],
    versions = ["1.66.1"],
)

load("@rules_rust//crate_universe:repositories.bzl", "crate_universe_dependencies")

crate_universe_dependencies(rust_version = "1.66.1")

This is fixed by #1781 ! Running into different issues now but will make new issues for those
