Enum rustc_passes::stability::InheritDeprecation[−][src]

enum InheritDeprecation {
    Yes,
    No,
}

Expand description

Whether to inherit deprecation flags for nested items. In most cases, we do want to inherit deprecation, because nested items rarely have individual deprecation attributes, and so should be treated as deprecated if their parent is. However, default generic parameters have separate deprecation attributes from their parents, so we do not wish to inherit deprecation in this case. For example, inheriting deprecation for T in Foo<T> would cause a duplicate warning arising from both Foo and T being deprecated.
