Struct cashweb_bitcoin::bip32::ExtendedPublicKey

pub struct ExtendedPublicKey { /* fields omitted */ }

A wrapper around PublicKey to allow Hierarchical Deterministic Wallets public key derivation.

Implementations

impl ExtendedPublicKey

pub fn new_master(public_key: PublicKey, chain_code: [u8; 32]) -> Self

Construct a new master public key.

pub fn get_public_key(&self) -> &PublicKey

Get the underlying PublicKey.

pub fn into_public_key(self) -> PublicKey

Convert into the underlying PublicKey.

pub fn as_parts(&self) -> (PublicKey, [u8; 32])

Convert into the PublicKey and chain code.

pub fn into_parts(self) -> (PublicKey, [u8; 32])

Convert into the PublicKey and chain code.

pub fn derive_public_path<C: Verification, P>(
    &self,
    secp: &Secp256k1<C>,
    path: &P
) -> Result<ExtendedPublicKey, DeriveError> where
    &'a P: IntoIterator<Item = &'a ChildNumber>, 

Attempts to derive an ExtendedPublicKey from a path.

The path must consist of an iterable collection of ChildNumbers.

pub fn derive_public_child<C: Verification>(
    &self,
    secp: &Secp256k1<C>,
    child_number: ChildNumber
) -> Result<ExtendedPublicKey, DeriveError>

Derive the child ExtendedPublicKey from a ChildNumber.
