#[non_exhaustive]

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

in_transaction: Option<InTransactionStatus>

Inner status, or None if no transaction is running
