David Tolnay 7f314acc34 Delete special handling of some expr kinds from print_let ... In all four of Break, Closure, Ret, Yeet, the needs_par_as_let_scrutinee is guaranteed to return true because the .precedence().order() of those expr kinds is <= AssocOp::LAnd.precedence(). The relevant functions in rustc_ast::util::parser are: fn needs_par_as_let_scrutinee(order: i8) -> bool { order <= prec_let_scrutinee_needs_par() as i8 } fn prec_let_scrutinee_needs_par() -> usize { AssocOp::LAnd.precedence() } The .precedence().order() of Closure is PREC_CLOSURE (-40) and of Break, Ret, Yeet is PREC_JUMP (-30). The value of AssocOp::LAnd.precedence() is 6. So this commit causes no change in behavior, only potentially performance by doing a redundant call to contains_exterior_struct_lit in those four cases. This is fine because Break, Closure, Ret, Yeet should be exceedingly rare in the position of a let scrutinee.		2023-12-08 15:14:44 -08:00
