Static rustc_lint_defs::builtin::PRIVATE_BOUNDS

pub static PRIVATE_BOUNDS: &Lint

The private_bounds lint detects types in a secondary interface of an item, that are more private than the item itself. Secondary interface of an item consists of bounds on generic parameters and where clauses, including supertraits for trait items.

Example

#![deny(private_bounds)]

struct PrivTy;
pub struct S
    where PrivTy:
{}

{{produces}}

Explanation

Having private types or traits in item bounds makes it less clear what interface the item actually provides.
