TxBuilder

This constructor can be used to instantiate a fake object. Only used for tests. Any attempt to actually use an object constructed this way will fail as there is no connected Rust object.

Add data as an output using OP_RETURN.

Fill-in the PSBT_GLOBAL_XPUB field with the extended keys contained in both the external and internal descriptors.

Add a recipient to the internal list of recipients.

Add a utxo to the internal list of unspendable utxos.

Add a utxo to the internal list of utxos that must be spent.

Add the list of outpoints to the internal list of UTXOs that must be spent.

Set whether or not the dust limit is checked.

Set a specific ChangeSpendPolicy. See TxBuilder::do_not_spend_change and TxBuilder::only_spend_change for some shortcuts. This method assumes the presence of an internal keychain, otherwise it has no effect.

Set the current blockchain height.

Do not spend change outputs.

Sets the address to drain excess coins to.

Spend all the available inputs. This respects filters like TxBuilder::unspendable and the change policy.

Set an absolute fee The fee_absolute method refers to the absolute transaction fee in Amount. If anyone sets both the fee_absolute method and the fee_rate method, the FeePolicy enum will be set by whichever method was called last, as the FeeRate and FeeAmount are mutually exclusive.

Set a custom fee rate.

Finish building the transaction.

Only spend utxos added by TxBuilder::add_utxo.

Use a specific nLockTime while creating the transaction.

Only spend change outputs.

The TxBuilder::policy_path is a complex API. See the Rust docs for complete information: https://docs.rs/bdk_wallet/latest/bdk_wallet/struct.TxBuilder.html#method.policy_path

Set an exact nSequence value.

Replace the recipients already added with a new list of recipients.

Replace the internal list of unspendable utxos with a new list.

Build a transaction with a specific version.
