Module bdk::database

Database types

This module provides the implementation of some defaults database types, along with traits that can be implemented externally to let Wallets use customized databases.

It’s important to note that the databases defined here only contains “blockchain-related” data. They can be seen more as a cache than a critical piece of storage that contains secrets and keys.

The currently recommended database is sled, which is a pretty simple key-value embedded database written in Rust. If the key-value-db feature is enabled (which by default is), this library automatically implements all the required traits for sled::Tree.
