bazel 0.7.0 issues

[mfarrugi]

I ran into

...
                rust_binary(name = 'hello')                    
        File "/home/marco/.cache/bazel/_bazel_marco/405dd47089fd4396034c2fe0895614dc/external/io_bazel_rules_rust/rust/rust.bzl", line 366, in _rust_binary_impl                                                                                               
                _setup_deps(ctx.attr.deps, ctx.label.name, outpu..., ...)                                                      
        File "/home/marco/.cache/bazel/_bazel_marco/405dd47089fd4396034c2fe0895614dc/external/io_bazel_rules_rust/rust/rust.bzl", line 142, in _setup_deps                                                                                                     
                set()                                          
The `set` constructor for depsets is deprecated and will be removed. Please use the `depset` constructor instead. You can temporarily enable the deprecated `set` constructor by passing the flag --incompatible_disallow_set_constructor=false.      

and assume other rules are similarly affected.

Is this being fixed already?

[katre]

I don't believe so. The fix is pretty simple: just replace all set(...) calls with depset(...).

Is this something you would be interested in taking on? It's a simple fix, but I'm not sure if anyone else will have time in the near future.

[mfarrugi]

This was actually handled by #50, so this is an issue with the setup docs being unclear about supported bazel versions (ie. rules_rust-0.0.5 only works up to bazel-0.6.1).

[hwright]

Perhaps it's worth cutting a new release and updating the docs?

[tomazos]

Hi, this doesn't work with latest bazel 0.9 for same reason as OP (The set constructor for depsets is deprecated and will be removed. Please use the depset constructor instead. You can temporarily enable the deprecated set constructor by passing the flag --incompatible_disallow_set_constructor=false.). Can you cut a new release with the fix? or post instructions on how to take master in the WORKSPACE?

[mfarrugi]

@tomazos To grab the latest you can do this:

http_archive(
    name = "io_bazel_rules_rust",
    # sha256 = # Will be a moving target for master
    strip_prefix = "rules_rust-master",
    urls = [
        "https://github.com/bazelbuild/rules_rust/archive/master.tar.gz",
    ],
)
load("@io_bazel_rules_rust//rust:repositories.bzl", "rust_repositories")

rust_repositories()

But you should refer to a particular commit and provide the sha256
