//! This crate is used for updating structures of the [`bdk_chain`] crate with data from electrum.
//!
//! The star of the show is the [`ElectrumExt::scan`] method, which scans for relevant blockchain
//! data (via electrum) and outputs updates for [`bdk_chain`] structures as a tuple of form:
//!
//! ([`bdk_chain::local_chain::Update`], [`RelevantTxids`], `keychain_update`)
//!
//! An [`RelevantTxids`] only includes `txid`s and no full transactions. The caller is
//! responsible for obtaining full transactions before applying. This can be done with
//! these steps:
//!
//! 1. Determine which full transactions are missing. The method [`missing_full_txs`] of
//! [`RelevantTxids`] can be used.
//!
//! 2. Obtaining the full transactions. To do this via electrum, the method
//! [`batch_transaction_get`] can be used.
//!
//! Refer to [`bdk_electrum_example`] for a complete example.
