⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.



A wrapper around reference that compares and hashes like a pointer. Can be used as a key in sets/maps indexed by pointers to avoid unsafe.
