Module bdk::blockchain::any

Runtime-checked blockchain types

This module provides the implementation of AnyBlockchain which allows switching the inner Blockchain type at runtime.

Example

In this example both wallet_electrum and wallet_esplora have the same type of Wallet<AnyBlockchain, MemoryDatabase>. This means that they could both, for instance, be assigned to a struct member.

let electrum_blockchain = ElectrumBlockchain::from(electrum_client::Client::new("...")?);
let wallet_electrum: Wallet<AnyBlockchain, _> = Wallet::new(
    "...",
    None,
    Network::Testnet,
    MemoryDatabase::default(),
    electrum_blockchain.into(),
)?;

let esplora_blockchain = EsploraBlockchain::new("...", None);
let wallet_esplora: Wallet<AnyBlockchain, _> = Wallet::new(
    "...",
    None,
    Network::Testnet,
    MemoryDatabase::default(),
    esplora_blockchain.into(),
)?;

When paired with the use of ConfigurableBlockchain, it allows creating wallets with any blockchain type supported using a single line of code:

let config = serde_json::from_str("...")?;
let blockchain = AnyBlockchain::from_config(&config)?;
let wallet = Wallet::new(
    "...",
    None,
    Network::Testnet,
    MemoryDatabase::default(),
    blockchain,
)?;
