🔬 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?

Trait for types providing lint checks.

Each check method checks a single syntax node, and should not invoke methods recursively (unlike Visitor). By default they do nothing.
