A segment of a path: an identifier, an optional lifetime, and a set of types.

Fields

name: Name

The identifier portion of this path segment.

parameters: Option<P<PathParameters>>

Type/lifetime parameters attached to this path. They come in two flavors: Path<A,B,C> and Path(A,B) -> C. Note that this is more than just simple syntactic sugar; the use of parens affects the region binding rules, so we preserve the distinction.

infer_types: bool

Whether to infer remaining type parameters, if any. This only applies to expression and pattern paths, and out of those only the segments with no type parameters to begin with, e.g. Vec::new is <Vec<..>>::new::<..>.
