A segment of a path: an identifier, an optional lifetime, and a set of types.
E.g. std
, String
or Box<T>

Type/lifetime parameters attached to this path. They come in
two flavors: Path<A,B,C>
and Path(A,B) -> C
.
None
means that no parameter list is supplied (Path
),
Some
means that parameter list is supplied (Path<X, Y>
)
but it can be empty (Path<>
).
P
is used as a size optimization for the common case with no parameters.
