Error (rule 'rust_library') doesn't contain declared provider 'CcInfo' for cargo raze deps

[timothyklim]

Hello!
I have an issue in my rust library as JNI after upgrading rules_rust to this commit #361:

load("@//:config.bzl", "rustc_flags")
load("@io_bazel_rules_rust//rust:rust.bzl", "rust_library")

rust_library(
    name = "somelib",
    srcs = ["src/lib.rs"],
    crate_root = "src/lib.rs",
    crate_type = "cdylib",
    rustc_flags = rustc_flags,
    deps = [
        "//cargo:jni",
    ],
    visibility = ["//visibility:public"],
)

bazel build:

Dependencies has been generated by cargo-raze v0.3.6.

Yes there is an obvious bug I wonder why it was not caught earlier.

[damienmg]

Ok it wasn't caught because it would be triggered only with staticlib / cdylib

Now it's working again. Thank you!
