pub struct Xpub { /* private fields */ }

Implementations

impl Xpub

pub fn decode(data: impl Borrow<[u8]>) -> Result<Xpub, XkeyDecodeError>

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

pub fn is_testnet(&self) -> bool

pub fn depth(&self) -> u8

pub fn child_number(&self) -> DerivationIndex

pub fn parent_fp(&self) -> XpubFp

pub fn identifier(&self) -> XpubId

Returns the HASH160 of the chaincode

pub fn fingerprint(&self) -> XpubFp

pub fn to_legacy_pk(&self) -> LegacyPk

Constructs ECDSA public key valid in legacy context (compressed by default).

pub fn to_compr_pk(&self) -> CompressedPk

Constructs ECDSA public key.

pub fn to_xonly_pk(&self) -> XOnlyPk

Constructs BIP340 public key matching internal public key representation.

pub fn derive_pub(&self, path: impl AsRef<[NormalIndex]>) -> Xpub

Attempts to derive an extended public key from a path.

The path argument can be any type implementing AsRef<ChildNumber>, such as DerivationPath, for instance.

pub fn ckd_pub_tweak(&self, child_no: NormalIndex) -> (Scalar, ChainCode)

Compute the scalar tweak added to this key to get a child key

pub fn ckd_pub(&self, child_no: NormalIndex) -> Xpub

Public->Public child key derivation

pub fn chain_code(&self) -> ChainCode

Trait Implementations

impl Clone for Xpub

fn clone(&self) -> Xpub

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Xpub

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

Formats the value using the given formatter.

impl Decode for Xpub

fn decode(reader: &mut impl Read) -> Result<Xpub, DecodeError>

fn deserialize(bytes: impl AsRef<[u8]>) -> Result<Self, PsbtError>

impl Display for Xpub

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

Formats the value using the given formatter.

impl Encode for Xpub

fn encode(&self, writer: &mut dyn Write) -> Result<usize, IoError>

impl FromStr for Xpub

type Err = XkeyParseError

The associated error which can be returned from parsing.

fn from_str(inp: &str) -> Result<Xpub, XkeyParseError>

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

impl Hash for Xpub

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Xpub

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