What went wrong

ALE should lint Rust code. It doesn't.

Reproducing the bug

I created a new project running cargo new --bin tid_test and modified it such that ALE should show me an error. After saving the file I expected ALE to show me the error I produced, it didn't.

I wonder if it has something to do with this:

$ cargo check --all-targets
error: no library targets found

Here's the cargo-related bug report: rust-lang/cargo#4685 The cargo version I am using is

$ cargo --version
cargo 0.23.0 (61fa02415 2017-11-22)

It does not work at all when creating a new project running cargo new --bin and works only after opening the file when creating a new project like this: cargo new.

Note, this might be very related to #1045.

I can reproduce it as well.

It looks like --all-targets doesn't work properly in cargo for who knows what reason. I'll turn it off by default.

Thanks, that was quick and it works for me now!
