Struct RegionIdExhaustedError 

pub struct RegionIdExhaustedError;

Error type returned when the process-wide region_id counter is exhausted.

This error is returned by the internal ID-issuance helper when the counter has reached usize::MAX and transitioned to the exhausted sentinel (0). After this point, all future Region::new/with_capacity calls will fail.
