Global map (unsigned transaction, xpubs, etc.)

inputs: Vec<HashMap<Vec<u8>, Vec<u8>>>

Input maps (one per input)

Output maps (one per output)

version: u8

Version (default: 0)

Implementations

impl PartiallySignedTransaction

pub fn new(unsigned_tx: &[u8]) -> GovernanceResult<Self>

Create a new PSBT from an unsigned transaction

pub fn add_input_data( &mut self, input_index: usize, key: Vec<u8>, value: Vec<u8>, ) -> GovernanceResult<()>

Add input data

pub fn add_output_data( &mut self, output_index: usize, key: Vec<u8>, value: Vec<u8>, ) -> GovernanceResult<()>

Add output data

pub fn add_partial_signature( &mut self, input_index: usize, pubkey: Vec<u8>, signature: Vec<u8>, ) -> GovernanceResult<()>

Add partial signature to an input

pub fn add_bip32_derivation( &mut self, input_index: usize, pubkey: Vec<u8>, derivation: Bip32Derivation, ) -> GovernanceResult<()>

Add BIP32 derivation path to an input

pub fn set_sighash_type( &mut self, input_index: usize, sighash_type: SighashType, ) -> GovernanceResult<()>

Set sighash type for an input

pub fn is_finalized(&self) -> bool

Check if PSBT is finalized (all inputs have final script sig/witness)

pub fn extract_transaction(&self) -> GovernanceResult<Vec<u8>>

Extract final transaction (throws error if not finalized)

pub fn serialize(&self) -> GovernanceResult<Vec<u8>>

Serialize PSBT to bytes

pub fn deserialize(data: &[u8]) -> GovernanceResult<Self>

Deserialize PSBT from bytes

Trait Implementations

impl Clone for PartiallySignedTransaction

fn clone(&self) -> PartiallySignedTransaction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartiallySignedTransaction

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

Formats the value using the given formatter.

impl PartialEq for PartiallySignedTransaction

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