Struct bdk_debug::descriptor::template::Bip86Public

pub struct Bip86Public<K: DerivableKey<Tap>>(pub K, pub Fingerprint, pub KeychainKind);

BIP86 public template. Expands to tr(key/{0,1}/*)

This assumes that the key used has already been derived with m/86'/0'/0' for Mainnet or m/86'/1'/0' for Testnet.

This template requires the parent fingerprint to populate correctly the metadata of PSBTs.

See Bip86 for a template that does the full derivation, but requires private data for the key.

Example

use bdk::template::Bip86Public;

let key = bitcoin::util::bip32::ExtendedPubKey::from_str("tpubDC2Qwo2TFsaNC4ju8nrUJ9mqVT3eSgdmy1yPqhgkjwmke3PRXutNGRYAUo6RCHTcVQaDR3ohNU9we59brGHuEKPvH1ags2nevW5opEE9Z5Q")?;
let fingerprint = bitcoin::util::bip32::Fingerprint::from_str("c55b303f")?;
let mut wallet = Wallet::new(
    Bip86Public(key.clone(), fingerprint, KeychainKind::External),
    Some(Bip86Public(key, fingerprint, KeychainKind::Internal)),
    Network::Testnet,
    MemoryDatabase::default()
)?;

assert_eq!(wallet.get_address(New)?.to_string(), "tb1pwjp9f2k5n0xq73ecuu0c5njvgqr3vkh7yaylmpqvsuuaafymh0msvcmh37");
assert_eq!(wallet.public_descriptor(KeychainKind::External)?.unwrap().to_string(), "tr([c55b303f/86'/1'/0']tpubDC2Qwo2TFsaNC4ju8nrUJ9mqVT3eSgdmy1yPqhgkjwmke3PRXutNGRYAUo6RCHTcVQaDR3ohNU9we59brGHuEKPvH1ags2nevW5opEE9Z5Q/0/*)#2p65srku");
