span: Span

name: Name

🔬 This is a nightly-only experimental API. (rustc_private)

Either "'a", referring to a named lifetime definition, or "" (aka keywords::Invalid), for elision placeholders.

HIR lowering inserts these placeholders in type paths that refer to type definitions needing lifetime parameters, &T and &mut T, and trait objects without ... + 'a.
