Extended private key

Fields

network: Network

The network this key is to be used on

depth: u8

How many derivations this key is from the master (which is 0)

parent_fingerprint: Fingerprint

Fingerprint of the parent key (0 for master)

child_number: ChildNumber

Child number of the key used to derive from parent (0 for master)

private_key: PrivateKey

Private key

chain_code: ChainCode

Chain code

Implementations

impl ExtendedPrivKey

pub fn new_master( network: Network, seed: &[u8] ) -> Result<ExtendedPrivKey, Error>

Construct a new master key from a seed value

pub fn derive_priv<C: Signing, P: AsRef<[ChildNumber]>>( &self, secp: &Secp256k1<C>, path: &P ) -> Result<ExtendedPrivKey, Error>

Attempts to derive an extended private key from a path.

The path argument can be both of type DerivationPath or Vec<ChildNumber>.

pub fn ckd_priv<C: Signing>( &self, secp: &Secp256k1<C>, i: ChildNumber ) -> Result<ExtendedPrivKey, Error>

Private->Private child key derivation

pub fn identifier<C: Signing>(&self, secp: &Secp256k1<C>) -> XpubIdentifier

Returns the HASH160 of the chaincode

pub fn fingerprint<C: Signing>(&self, secp: &Secp256k1<C>) -> Fingerprint

Returns the first four bytes of the identifier

Trait Implementations

impl Clone for ExtendedPrivKey

fn clone(&self) -> ExtendedPrivKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExtendedPrivKey

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

Formats the value using the given formatter.

impl Display for ExtendedPrivKey

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

Formats the value using the given formatter.

impl FromStr for ExtendedPrivKey

type Err = Error

The associated error which can be returned from parsing.

fn from_str(inp: &str) -> Result<ExtendedPrivKey, Error>

Parses a string s to return a value of this type.

impl PartialEq for ExtendedPrivKey

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

This method tests for self and other values to be equal, and is used by ==.

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

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