Module bdk_chain::keychain

Expand description

Module for keychain related structures.

A keychain here is a set of application-defined indexes for a miniscript descriptor where we can derive script pubkeys at a particular derivation index. The application’s index is simply anything that implements Ord.

KeychainTxOutIndex indexes script pubkeys of keychains and scans in relevant outpoints (that has a txout containing an indexed script pubkey). Internally, this uses SpkTxOutIndex, but also maintains “revealed” and “lookahead” index counts per keychain.




Type Aliases§

  • A tuple of keychain index and T representing the indexed value.
  • A tuple of keychain K, derivation index (u32) and a T associated with them.
