Type Alias bitcoin::bip32::ExtendendPrivKey

pub type ExtendendPrivKey = Xpriv;

👎Deprecated since 0.31.0: use xpriv instead

The old name for xpriv, extended public key (with a released typo in it).

Aliased Type

Implementations

impl Xpriv

pub fn new_master( network: impl Into<NetworkKind>, seed: &[u8] ) -> Result<Xpriv, Error>

Construct a new master key from a seed value

pub fn to_priv(self) -> PrivateKey

Constructs ECDSA compressed private key matching internal secret key representation.

pub fn to_keypair<C: Signing>(self, secp: &Secp256k1<C>) -> Keypair

Constructs BIP340 keypair for Schnorr signatures and Taproot use matching the internal secret key representation.

pub fn derive_priv<C: Signing, P: AsRef<[ChildNumber]>>( &self, secp: &Secp256k1<C>, path: &P ) -> Result<Xpriv, 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 decode(data: &[u8]) -> Result<Xpriv, Error>

Decoding extended private key from binary data according to BIP 32

pub fn encode(&self) -> [u8; 78]

Extended private key binary encoding according to BIP 32

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

Returns the HASH160 of the public key belonging to the xpriv

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

Returns the first four bytes of the identifier

Trait Implementations

impl Clone for Xpriv

fn clone(&self) -> Xpriv

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Xpriv

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Xpriv

fn deserialize<D>(deserializer: D) -> Result<Xpriv, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Xpriv

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

Formats the value using the given formatter.

impl FromStr for Xpriv

type Err = Error

The associated error which can be returned from parsing.

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

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

impl GetKey for Xpriv

type Error = GetKeyError

An error occurred while getting the key.

fn get_key<C: Signing>( &self, key_request: KeyRequest, secp: &Secp256k1<C> ) -> Result<Option<PrivateKey>, Self::Error>

Attempts to get the private key for key_request.

impl PartialEq<Xpriv> for Xpriv

fn eq(&self, other: &Xpriv) -> 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.

impl Serialize for Xpriv

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Xpriv

impl Eq for Xpriv

impl StructuralEq for Xpriv
