scriptPubKey()

scriptPubKey(Descriptor<Definite>|WshInfo|TapInfo|Address|Script) -> ScriptPubKey

Get the scriptPubKey to be used in a transaction output.

Also accessible using the script_pubkey field.

Errors: When called with a Descriptor<Indefinite>.

Rust source code: src/stdlib/btc.rs:256

explicitScript()

explicitScript(Descriptor<Definite>|WshInfo) -> Script

Get the underlying Script, before any hashing is done.

• For Wpkh, Pkh and Bare descriptors, this is the scriptPubkey
• For Wsh and ShWsh descriptors, this is the witnessScript
• For Sh and ShWpkh descriptors, this is the redeemScript
• For WshInfo, this is the witnessScript

Also accessible using the explicit_script field.

Errors:

• When called with a Descriptor<Indefinite>.
• When called with a Descriptor<Tr>. Taproot doesn't have a single explicit script, but rather a tree of them. These can be obtained using Descriptor->scripts/Descriptor->script_tree and TapInfo->scripts/TapInfo->script_tree.
