⚙️ 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.

Stores the user-given substs to reach some fully qualified path (e.g., <T>::Item or <T as Trait>::Item).
