unused_crate_dependencies
needs to be removed from the unused
lint group, I didn't notice this when reviewing https://github.com/rust-lang/rust/pull/72342.
Otherwise it can be enabled in a blanket way without enabling unused_crate_dependencies
specifically, which is undesirable given the amount of redundant options passed by Cargo.
Yeah this is the reason it's not on by default. We still need to work out if/how it can be used with cargo in a reasonable way.
Adding it to unused
made sense to me but I didn't think through the fallout.
@svartalf Though TBH I'm a bit confused - what targets is Cargo passing dev-dependencies to aside from tests? I would have thought your case would be OK.
Hm, I think there may be another bug that -Wunused-crate-dependencies
isn't seeing uses in #[test]
blocks. At the very least it needs a test for that.
As far as I can tell, this issue wasn't fixed, unused_crate_dependencies
was just removed from the unused
group.
The functionality of unused_crate_dependencies
is still desirable!
unused_crate_dependencies
lint introduced in https://github.com/rust-lang/rust/pull/72342 causes false positives for[dev-dependencies]
.To reproduce:
I expected to execute
cargo +nightly test
correctly.Instead, this happened:
I expect
dev-dependencies
to be ignored by this lint, because they are in fact used intests/
modules. "remove the dependency or adduse version_sync as _;
" help message is also unhelpful, because it will cause unresolved imports forcargo build
and similar commands.Meta
