Struct rustc_ast::ast::PathSegment

source ·

pub struct PathSegment {
    pub ident: Ident,
    pub id: NodeId,
    pub args: Option<P<GenericArgs>>,
}

Expand description

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

E.g., std, String or Box<T>.

Fields§

§ident: Ident

The identifier portion of this path segment.

§id: NodeId§args: Option<P<GenericArgs>>

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.
