  "message": "Use fewer intermediate functions for short backtraces in queries\n\nIf we make sure that `compute_fn` in the query\u0027s vtable is actually named\n`__rust_begin_short_backtrace`, we can avoid the need for some additional\nintermediate functions and stack frames.\n\nThis is similar to how the `get_query_incr` and `get_query_non_incr` functions\nare actually named `__rust_end_short_backtrace`.\n",
