Closure transaction's TransactionError and it's wrapped error

[szattila98]

Hello, I have been trying to use the closure transaction API, mentioned in the docs as the preferred option, and on error the closure returns a TransactionError<WrappedError>. WrappedError is the type I specify in the E spot within the turbofish ::<_, T, E> if I understand it right. My question is, how can I unwrap the WrappedError from the TransactionError? Also what is the first type in the turbofish, the _ ?

Oh I missed the part that the TransactionError is an enum, so it is easy to unwrap with match. The _ in the tutorial turbofish is probably the transaction closure signature if I understand it correctly.
