Struct ergo_lib::wallet::ext_pub_key::ExtPubKey

pub struct ExtPubKey {
    pub public_key: EcPoint,
    pub derivation_path: DerivationPath,
    /* private fields */
}

Extended public key implemented according to BIP-32

Fields

public_key: EcPoint

Parsed public key (EcPoint)

derivation_path: DerivationPath

Derivation path for this extended public key

Implementations

impl ExtPubKey

pub fn new( public_key_bytes: PubKeyBytes, chain_code: ChainCode, derivation_path: DerivationPath ) -> Result<Self, SigmaParsingError>

Create ExtPubKey from public key bytes (from SEC1 compressed), chain code and derivation path

pub fn pub_key_bytes(&self) -> PubKeyBytes

Public key bytes of the ExtPubKey

pub fn chain_code(&self) -> ChainCode

Chain code of the ExtPubKey

pub fn child(&self, index: ChildIndexNormal) -> Self

Soft derivation of the child public key with a given index

pub fn derive(&self, up_path: DerivationPath) -> Result<Self, ExtPubKeyError>

Derive a new extended pub key based on the provided derivation path

Trait Implementations

impl Clone for ExtPubKey

fn clone(&self) -> ExtPubKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExtPubKey

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

Formats the value using the given formatter.

impl From<ExtPubKey> for Address

fn from(epk: ExtPubKey) -> Self

Converts to this type from the input type.

impl PartialEq<ExtPubKey> for ExtPubKey

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