Struct rustc_lint::builtin::UnusedBrokenConst

pub struct UnusedBrokenConst;

🔬 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 constants that are erroneous. Without this lint, we might not get any diagnostic if the constant is unused within this crate, even though downstream crates can't use it without producing an error.
