Struct bitcoin_scripts::WitnessScript

pub struct WitnessScript(_);

A content of the script from witness structure; en equivalent of redeemScript for witness-based transaction inputs. However, unlike RedeemScript, WitnessScript produce SHA256-based hashes of WScriptHash type.

Witness script can be nested within the redeem script in legacy P2WSH-in-P2SH schemes; for this purpose use RedeemScript::from method.

Implementations

impl WitnessScript

pub fn script_hash(&self) -> WScriptHash

Computes script commitment which participates in Witness or RedeemScript.

pub fn to_p2wsh(&self) -> PubkeyScript

Generates PubkeyScript matching given witnessScript for native SegWit outputs.

pub fn to_p2sh_wsh(&self) -> PubkeyScript

Generates PubkeyScript matching given witnessScript for legacy P2WSH-in-P2SH outputs.
