pub struct TxInputsBuilder { /* private fields */ }

Implementations

impl TxInputsBuilder

pub fn new() -> Self

pub fn add_key_input( &mut self, hash: &Ed25519KeyHash, input: &TransactionInput, amount: &Value )

We have to know what kind of inputs these are to know what kind of mock witnesses to create since

1. mock witnesses have different lengths depending on the type which changes the expecting fee
2. Witnesses are a set so we need to get rid of duplicates to avoid over-estimating the fee

pub fn add_script_input( &mut self, hash: &ScriptHash, input: &TransactionInput, amount: &Value )

👎Deprecated since 11.2.0: Use .add_native_script_input or .add_plutus_script_input instead.

!!! DEPRECATED !!! This function can make a mistake in choosing right input index. Use .add_native_script_input or .add_plutus_script_input instead. This method adds the input to the builder BUT leaves a missing spot for the witness native script

After adding the input with this method, use .add_required_native_input_scripts and .add_required_plutus_input_scripts to add the witness scripts

Or instead use .add_native_script_input and .add_plutus_script_input to add inputs right along with the script, instead of the script hash

pub fn add_native_script_input( &mut self, script: &NativeScript, input: &TransactionInput, amount: &Value )

This method will add the input to the builder and also register the required native script witness

pub fn add_plutus_script_input( &mut self, witness: &PlutusWitness, input: &TransactionInput, amount: &Value )

This method will add the input to the builder and also register the required plutus witness

pub fn add_bootstrap_input( &mut self, hash: &ByronAddress, input: &TransactionInput, amount: &Value )

pub fn add_input( &mut self, address: &Address, input: &TransactionInput, amount: &Value )

Note that for script inputs this method will use underlying generic .add_script_input which leaves a required empty spot for the script witness (or witnesses in case of Plutus). You can use .add_native_script_input or .add_plutus_script_input directly to register the input along with the witness.

pub fn count_missing_input_scripts(&self) -> usize

Returns the number of still missing input scripts (either native or plutus) Use .add_required_native_input_scripts or .add_required_plutus_input_scripts to add the missing scripts

pub fn add_required_native_input_scripts( &mut self, scripts: &NativeScripts ) -> usize

Try adding the specified scripts as witnesses for ALREADY ADDED script inputs Any scripts that don’t match any of the previously added inputs will be ignored Returns the number of remaining required missing witness scripts Use .count_missing_input_scripts to find the number of still missing scripts

pub fn add_required_plutus_input_scripts( &mut self, scripts: &PlutusWitnesses ) -> usize

👎Deprecated since 11.2.0: This function can make a mistake in choosing right input index. Use .add_required_script_input_witnesses instead.

pub fn get_ref_inputs(&self) -> TransactionInputs

pub fn get_native_input_scripts(&self) -> Option<NativeScripts>

Returns a copy of the current script input witness scripts in the builder

pub fn get_plutus_input_scripts(&self) -> Option<PlutusWitnesses>

Returns a copy of the current plutus input witness scripts in the builder. NOTE: each plutus witness will be cloned with a specific corresponding input index

pub fn len(&self) -> usize

pub fn add_required_signer(&mut self, key: &Ed25519KeyHash)

pub fn add_required_signers(&mut self, keys: &RequiredSigners)

pub fn total_value(&self) -> Result<Value, JsError>

pub fn inputs(&self) -> TransactionInputs

pub fn inputs_option(&self) -> Option<TransactionInputs>
