Couldn't generate the documentation (extern_prelude)

[adjivas]

Hello,

When I compile the documentation from futures-channel project, this error append:

cargo doc
 Documenting futures-channel v0.2.1 (file:///private/tmp/adjivas/futures-rs/futures-channel)
error[E0658]: access to extern crates through prelude is experimental (see issue #44660)
  |
  = help: add #![feature(extern_prelude)] to the crate attributes to enable

error: Could not document `futures-channel`.

Caused by:
  process didn't exit successfully: `rustdoc --crate-name futures_channel futures-channel/src/lib.rs -o /private/tmp/adjivas/futures-rs/target/doc --cfg feature="default" --cfg feature="futures-core" --cfg feature="std" -L dependency=/private/tmp/adjivas/futures-rs/target/debug/deps --extern futures_core=/private/tmp/adjivas/futures-rs/target/debug/deps/libfutures_core-670bf32b5273b58b.rmeta` (exit code: 101)

Of course if I add doc = false to Cargo.toml manifest from futures-channel or #![feature(extern_prelude)] to lib.rs that solve the compilation.

My versions are:

• rustc 1.27.0-nightly (8a37c75a3 2018-05-02)
• cargo 1.27.0-nightly (122fd5be5 2018-04-28)

Was fixed as part of #1003

That right, I close my issue, thank you!

There is any regression ? I have this repetition on this log

[Nemo157]

There hasn't been a new release of futures 0.2 since #1003 was merged, you will either have to wait till that happens, or switch to depending on futures = { git = "https://github.com/rust-lang-nursery/futures-rs" } in the meantime.

Okay! Thank's for the information
