Struct fabric_contract::blockchain::TransactionContext

pub struct TransactionContext { /* fields omitted */ }

Represents a transaction

This can be used to obtain information about the current transaction that trigger a contract function to be executed.

Timestamp and MSPID are two important fields

Example

pub fn myTransactionFn(){
  let tx = fabric_contract::blockchain::TransactionContext::current_transaction();

  let id = tx.get_id();
  let timestamp = tx.get_timestamp();
  let mspid = tx.get_peer_mspid();
}
