Struct rustc_ast::ast::PathSegment

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

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.

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.
