Type Definition lightning::chain::transaction::TransactionData

type TransactionData<'a> = [(usize, &'a Transaction)];

Transaction data where each item consists of a transaction reference paired with the index of the transaction within a block.

Useful for passing enumerated transactions from a block, possibly filtered, in order to retain the transaction index.
