Struct syntax::ast::PathSegment
[−]
[src]
pub struct PathSegment { pub identifier: Ident, pub span: Span, pub parameters: Option<P<PathParameters>>, }
A segment of a path: an identifier, an optional lifetime, and a set of types.
E.g. std
, String
or Box<T>
Fields
identifier: Ident
The identifier portion of this path segment.
span: Span
Span of the segment identifier.
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
.
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.
