Static PRIVATE_INTERFACES

pub static PRIVATE_INTERFACES: &Lint

The private_interfaces lint detects types in a primary interface of an item, that are more private than the item itself. Primary interface of an item is all its interface except for bounds on generic parameters and where clauses.

Example

#![deny(private_interfaces)]
struct SemiPriv;

mod m1 {
    struct Priv;
    impl crate::SemiPriv {
        pub fn f(_: Priv) {}
    }
}

{{produces}}

Explanation

Having something private in primary interface guarantees that the item will be unusable from outer modules due to type privacy.
