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: HirIdres: Resargs: 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::<..>.

Implementations

Converts an identifier to the corresponding segment.

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.
