Struct rustc_lint::builtin::TypeAliasBounds

pub struct TypeAliasBounds;

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Lint for trait and lifetime bounds in type aliases being mostly ignored: They are relevant when using associated types, but otherwise neither checked at definition site nor enforced at use site.
