SpendFinalizer

pczt::roles::spend_finalizer

Struct SpendFinalizer 

Source 
pub struct SpendFinalizer { /* private fields */ }
Available on crate feature spend-finalizer only.

Implementations§

Source§

impl SpendFinalizer

Source

pub fn new(pczt: Pczt) -> Self

Instantiates the Spend Finalizer role with the given PCZT.

Source

pub fn with_sighash_policy(self, sighash_policy: SighashPolicy) -> Self

Sets the sighash policy that this Spend Finalizer applies to partial signatures.

The default is [SighashPolicy::ALL_ONLY]; see [SighashPolicy] for why.

This policy governs which signatures are assembled into script_sigs; it does not protect whoever produced them. A partial signature that does not commit to the whole transaction can be lifted out of the PCZT and used directly, without this role ever running, so the decision that protects a signer is the Signer’s own Signer::with_transparent_sighash_policy.

Source

pub fn finalize_spends(self) -> Result<Pczt, Error>

Finalizes the spends of the PCZT.
