Struct hdwallet::ChildPubKey

pub struct ChildPubKey {
    pub key_index: KeyIndex,
    pub extended_key: ExtendedPubKey,
}

ChildPubKey derive from ExtendedPubKey, or from ChildPrivKey

Examples

use hdwallet::{ExtendedPrivKey, ExtendedPubKey, ChildPubKey, KeyIndex};

let priv_key = ExtendedPrivKey::random().unwrap();
let pub_key = ExtendedPubKey::from_private_key(&priv_key).unwrap();

// Derive public normal child key
let normal_key_index = KeyIndex::Normal(0);
let child_pub_key = pub_key.derive_public_key(normal_key_index).unwrap();

// Generate public child key from private child key
let child_priv_key = priv_key.derive_private_key(KeyIndex::Normal(0)).unwrap();
assert_eq!(child_pub_key, ChildPubKey::from_private_key(&child_priv_key).unwrap());

Fields
