Struct Bip49

pub struct Bip49<K: DerivableKey<Segwitv0>>(pub K, pub KeychainKind);

BIP49 template. Expands to sh(wpkh(key/49'/{0,1}'/0'/{0,1}/*))

Since there are hardened derivation steps, this template requires a private derivable key (generally a xprv/tprv).

See Bip49Public for a template that can work with a xpub/tpub.

Example

use bdk_wallet::template::Bip49;

let key = bitcoin::bip32::Xpriv::from_str("tprv8ZgxMBicQKsPeZRHk4rTG6orPS2CRNFX3njhUXx5vj9qGog5ZMH4uGReDWN5kCkY3jmWEtWause41CDvBRXD1shKknAMKxT99o9qUTRVC6m")?;
let mut wallet = Wallet::create(
    Bip49(key.clone(), KeychainKind::External),
    Bip49(key, KeychainKind::Internal),
)
.network(Network::Testnet)
.create_wallet_no_persist()?;

assert_eq!(wallet.next_unused_address(KeychainKind::External).to_string(), "2N4zkWAoGdUv4NXhSsU8DvS5MB36T8nKHEB");
assert_eq!(wallet.public_descriptor(KeychainKind::External).to_string(), "sh(wpkh([c55b303f/49'/1'/0']tpubDDYr4kdnZgjjShzYNjZUZXUUtpXaofdkMaipyS8ThEh45qFmhT4hKYways7UXmg6V7het1QiFo9kf4kYUXyDvV4rHEyvSpys9pjCB3pukxi/0/*))#s9vxlc8e");
