Implementations§
Source§impl<S: ErgoBoxAssets + ErgoBoxId + Clone> TxBuilder<S>
impl<S: ErgoBoxAssets + ErgoBoxId + Clone> TxBuilder<S>
Sourcepub fn new(
box_selection: BoxSelection<S>,
output_candidates: Vec<ErgoBoxCandidate>,
current_height: u32,
fee_amount: BoxValue,
change_address: Address,
) -> TxBuilder<S>
pub fn new( box_selection: BoxSelection<S>, output_candidates: Vec<ErgoBoxCandidate>, current_height: u32, fee_amount: BoxValue, change_address: Address, ) -> 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,
will be given to miners,
Sourcepub fn box_selection(&self) -> BoxSelection<S>
pub fn box_selection(&self) -> BoxSelection<S>
Get inputs
Sourcepub fn data_inputs(&self) -> Vec<DataInput>
pub fn data_inputs(&self) -> Vec<DataInput>
Get data inputs
Sourcepub fn output_candidates(&self) -> Vec<ErgoBoxCandidate>
pub fn output_candidates(&self) -> Vec<ErgoBoxCandidate>
Get outputs
Sourcepub fn current_height(&self) -> u32
pub fn current_height(&self) -> u32
Get current height
Sourcepub fn fee_amount(&self) -> BoxValue
pub fn fee_amount(&self) -> BoxValue
Get fee amount
Sourcepub fn change_address(&self) -> Address
pub fn change_address(&self) -> Address
Get change
Sourcepub fn set_data_inputs(&mut self, data_inputs: Vec<DataInput>)
pub fn set_data_inputs(&mut self, data_inputs: Vec<DataInput>)
Set transaction’s data inputs
Sourcepub fn set_context_extension(
&mut self,
box_id: BoxId,
context_extension: ContextExtension,
)
pub fn set_context_extension( &mut self, box_id: BoxId, context_extension: ContextExtension, )
Set context extension for a given input
Sourcepub fn estimate_tx_size_bytes(&self) -> Result<usize, TxBuilderError>
pub fn estimate_tx_size_bytes(&self) -> Result<usize, TxBuilderError>
Estimated serialized transaction size in bytes after signing (assuming P2PK box spending)
Sourcepub fn set_token_burn_permit(&mut self, tokens: Vec<Token>)
pub fn set_token_burn_permit(&mut self, tokens: Vec<Token>)
Permits the burn of the given token amount, i.e. allows this token amount to be omitted in the outputs
Sourcepub fn build(self) -> Result<UnsignedTransaction, TxBuilderError>
pub fn build(self) -> Result<UnsignedTransaction, TxBuilderError>
Build the unsigned transaction
