Struct lwk_signer::SwSigner

pub struct SwSigner { /* private fields */ }

A software signer

Implementations

impl SwSigner

pub fn new(mnemonic: &str, is_mainnet: bool) -> Result<Self, NewError>

Creates a new software signer from the given mnemonic.

Takes also a flag if the network is mainnet so that generated extended keys are in the correct form xpub/tpub (there is no need to discriminate between regtest and testnet)

pub fn random(is_mainnet: bool) -> Result<(Self, Mnemonic), NewError>

pub fn from_xprv(xprv: Xpriv) -> Self

pub fn xpub(&self) -> Xpub

pub fn seed(&self) -> Option<[u8; 64]>

pub fn mnemonic(&self) -> Option<Mnemonic>

pub fn fingerprint(&self) -> Fingerprint

Trait Implementations

impl Clone for SwSigner

fn clone(&self) -> SwSigner

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SwSigner

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

Formats the value using the given formatter.

impl Signer for SwSigner

type Error = SignError

fn sign( &self, pset: &mut PartiallySignedTransaction ) -> Result<u32, Self::Error>

Try to sign the given pset, mutating it in place. returns how many signatures were added or overwritten

fn derive_xpub(&self, path: &DerivationPath) -> Result<Xpub, Self::Error>

Derive an xpub from the master, path can contains hardened derivations

fn slip77_master_blinding_key(&self) -> Result<MasterBlindingKey, Self::Error>

Return the slip77 master blinding key

fn xpub(&self) -> Result<Xpub, Self::Error>

Return the master xpub of the signer

fn identifier(&self) -> Result<XKeyIdentifier, Self::Error>

Return the full identifier of the signer

fn fingerprint(&self) -> Result<Fingerprint, Self::Error>

Return the fingerprint of the signer (4 bytes)

fn keyorigin_xpub( &self, bip: Bip, is_mainnet: bool ) -> Result<String, Self::Error>

Return keyorigin and xpub, like “[73c5da0a/84h/1h/0h]tpub…”

fn is_mainnet(&self) -> Result<bool, Self::Error>
