fixed doctest for transactions with tree tuples
//! to the processed `Tree`.
//!
//! ```
-//! use sled::{Config, Transactional};
+//! # use sled::{transaction::{TransactionResult, Transactional}, Config};
+//! # fn main() -> TransactionResult<()> {
//!
//! let config = Config::new().temporary(true);
//! let db = config.open().unwrap();
//! processed_item.extend_from_slice(&unprocessed_item);
//! processed.insert(b"k3", processed_item)?;
//! Ok(())
-//! })
-//! .unwrap();
+//! })?;
//!
//! assert_eq!(unprocessed.get(b"k3").unwrap(), None);
//! assert_eq!(&processed.get(b"k3").unwrap().unwrap(), b"yappin' ligers");
+//! # Ok(())
+//! # }
//! ```
