As reported in #30827 and #84584, marking a re-export (
pub use
) with#[deprecated]
does not produce a warning for consumers. In fact, there are instances of this in thecore
andstd
crates (see past issue #82080 where this caused some confusion).This change modifies the stability annotation visitor to mark
#[deprecated]
annotations onuse
statements withAnnotationKind::DeprecationProhibited
so that library developers are aware that the annotation is not warning their users as expected.
