A path to a type definition (module::module::...::Type), or an associated type, e.g. <Vec<T> as Trait>::Type or <T>::Target.

Type parameters may be stored in each PathSegment.

TraitObject(HirVec<PolyTraitRef>, Lifetime)

🔬 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?

Typeof(AnonConst)

🔬 This is a nightly-only experimental API. (rustc_private)

Unused for now

Infer

🔬 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?

TyKind::Infer means the type should be inferred instead of it having been specified. This can appear anywhere in a type.

Err

🔬 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?

Placeholder for a type that has failed to be defined.
