Expand description
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.
hir_id: HirId
§res: Res
§args: Option<&'hir GenericArgs<'hir>>
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_args: 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::<..>
.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
