Support both [[bin]] and [lib] together?

% cargo check
extra arguments to `rustc` can only be passed to one target, consider filtering
the package by passing e.g. `--lib` or `--bin NAME` to specify a single target

Isn't there any way to support both [[bin]] and [lib] in one go? cargo build just works, so I'd expect cargo check to be drop-in replacement.

Yeah, this is the same error message that you'll receive if you ran cargo rustc -- -Zno-trans.

I normally work around this by doing something like cargo check --lib.
I'm not sure if there is a way to get cargo rustc to behave more like cargo build when it comes to this.

Maybe we should escalate to cargo devs?

The problem with always running cargo check --lib is that it excludes the main.rs file if you have one. This means that there currently isn't a way to run a generic cargo check command that will automatically build the project for editor linter support. A bit disappointing. I suppose I'll go back to cargo build.

My workaround for this was to split my project into several crates, with the top-level crate being bin-only and the rest being libs. However, this means that you have to append -p to your check invocation to lint the other crates.

And what about the test targets... I wanna check those too. 😞
