Struct ExtendedPublicKey

pub struct ExtendedPublicKey { /* private fields */ }

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], ) -> ExtendedPublicKey

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, P>( &self, secp: &Secp256k1<C>, path: &P, ) -> Result<ExtendedPublicKey, DeriveError>

where C: Verification, &'a P: for<'a> 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>( &self, secp: &Secp256k1<C>, child_number: ChildNumber, ) -> Result<ExtendedPublicKey, DeriveError>

where C: Verification,

Derive the child ExtendedPublicKey from a ChildNumber.

Trait Implementations

impl Clone for ExtendedPublicKey

fn clone(&self) -> ExtendedPublicKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExtendedPublicKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for ExtendedPublicKey

fn eq(&self, other: &ExtendedPublicKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
