struct sun::ast::LifetimeParameter

One lifetime parameter, as written between the angle brackets with a leading apostrophe, before any type parameters:

<'a> function pick<'a>(...) <'a, T> class Pair<'a, T> { ... }

A lifetime names the stack frame a <'a> lambda's environment or a ref 'a T referent lives in, so two positions in one signature can be declared to share it. Lifetimes are erased before codegen: they never distinguish types, emitted symbols, or generic specializations.
