Struct rustc::hir::PathSegment [−][src]
pub struct PathSegment { pub ident: Ident, pub args: Option<P<GenericArgs>>, pub infer_types: bool, }
🔬 This is a nightly-only experimental API. (rustc_private

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

The identifier portion of this path segment.

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

instead?
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::<..>
.
