I suspect this macro was around before `TypeFoldable`/`TypeVisitable` were derivable. But now it's only used for two types, `Result` and `Option`. Removing the macro and implementing the traits for those types by hand makes the code much simpler.
They both allow for a lifetime other than `'tcx`, but this isn't needed.
This avoids `rustc_data_structures` depending on `serde_json` which allows it to be compiled much earlier, unlocking most of rustc.
…ros, r=lcnr Clean up traversal macros The declarative macros relating to type folding and visiting can be simplified. r? `@lcnr`
…bject-notationing, r=fee1-dead Don't use `serde_json` to serialize a simple JSON object This avoids `rustc_data_structures` depending on `serde_json` which allows it to be compiled much earlier, unlocking most of rustc. This used to not matter, but after rust-lang#110407 we're not blocked on fluent anymore, which means that it's now a blocking edge.  This saves a few more seconds. cc `@Zoxc` who added it recently
…ram, r=petrochenkov Encode def span for `ConstParam` Fixes rust-lang#110206 r? `@petrochenkov`
…i-obk Check freeze with right param-env in `deduced_param_attrs` We're checking if a trait (`Freeze`) holds in a polymorphic function, but not using that function's own (reveal-all) param-env. This causes us to try to eagerly normalize a specializable projection type that has no default value, which causes an ICE. Fixes rust-lang#110171
