Struct ergo_lib::wallet::tx_builder::TxBuilder

pub struct TxBuilder<S: ErgoBoxAssets> { /* fields omitted */ }

Unsigned transaction builder

Implementations

impl<S: ErgoBoxAssets + ErgoBoxId + Clone> TxBuilder<S>

pub fn new(
    box_selection: BoxSelection<S>,
    output_candidates: Vec<ErgoBoxCandidate>,
    current_height: u32,
    fee_amount: BoxValue,
    change_address: Address,
    min_change_value: BoxValue
) -> TxBuilder<S>

Creates new TxBuilder box_selection - selected input boxes (via super::box_selector::BoxSelector) output_candidates - output boxes to be "created" in this transaction, current_height - chain height that will be used in additionally created boxes (change, miner's fee, etc.), fee_amount - miner's fee (higher values will speed up inclusion in blocks), change_address - change (inputs - outputs) will be sent to this address, min_change_value - minimal value of the change to be sent to change_address, value less than that will be given to miners,

pub fn box_selection(&self) -> BoxSelection<S>

Get inputs

pub fn data_inputs(&self) -> Vec<DataInput>

Get data inputs

pub fn output_candidates(&self) -> Vec<ErgoBoxCandidate>

Get outputs

pub fn current_height(&self) -> u32

Get current height

pub fn fee_amount(&self) -> BoxValue

Get fee amount

pub fn change_address(&self) -> Address

Get change

pub fn min_change_value(&self) -> BoxValue

Get min change value

pub fn set_data_inputs(&mut self, data_inputs: Vec<DataInput>)

Set transaction's data inputs

pub fn estimate_tx_size_bytes(&self) -> Result<usize, TxBuilderError>

Estimated serialized transaction size in bytes after signing (assuming P2PK box spending)

pub fn build(self) -> Result<UnsignedTransaction, TxBuilderError>

Build the unsigned transaction

Trait Implementations

impl<S: Clone + ErgoBoxAssets> Clone for TxBuilder<S>

pub fn clone(&self) -> TxBuilder<S>

Returns a copy of the value.

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

Performs copy-assignment from source.
