🔬 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?

Represents the projection of an associated type. In explicit UFCS form this would be written <T as Trait<..>>::N.

Fields
