[−][src]Static rustc_lint::builtin::PUB_USE_OF_PRIVATE_EXTERN_CRATE
pub static PUB_USE_OF_PRIVATE_EXTERN_CRATE: &'static Lint
The pub_use_of_private_extern_crate lint detects a specific
situation of re-exporting a private extern crate.
Example
ⓘThis example deliberately fails to compile
extern crate core; pub use core as reexported_core;
{{produces}}
Explanation
A public use declaration should not be used to publicly re-export a
private extern crate. pub extern crate should be used instead.
This was historically allowed, but is not the intended behavior according to the visibility rules. This is a future-incompatible lint to transition this to a hard error in the future. See issue #34537 for more details.
