Rollup merge ofrust-lang#127134 - tgross35:typeid-debug, r=Nilstrieb
Print `TypeId` as a `u128` for `Debug`Since <rust-lang#121358>, `TypeId` is represented as a `(u64, u64)`. This also made the debug implementation a lot larger, which is especially apparent with pretty formatting.Change this to convert the inner value back to a `u128` and then print as a tuple struct to make this less noisy.Current: TypeId { t: (1403077013027291752, 4518903163082958039) } TypeId { t: ( 1403077013027291752, 4518903163082958039, ), }New: TypeId(25882202575019293479932656973818029271) TypeId( 25882202575019293479932656973818029271, )
