Implementations§

Source§

impl Updater

Source

pub fn update_orchard_with<F>(self, f: F) -> Result<Self, OrchardError>
where F: FnOnce(Updater<'_>) -> Result<(), UpdaterError>,

Available on crate feature orchard only.

Updates the Orchard bundle with information in the given closure.

Source

pub fn update_ironwood_with<F>(self, f: F) -> Result<Self, OrchardError>
where F: FnOnce(Updater<'_>) -> Result<(), UpdaterError>,

Available on crate feature orchard only.

Updates the Ironwood bundle with information in the given closure.

Source§

impl Updater

Source

pub fn update_sapling_with<F>(self, f: F) -> Result<Self, SaplingError>
where F: FnOnce(Updater<'_>) -> Result<(), UpdaterError>,

Available on crate feature sapling only.

Updates the Sapling bundle with information in the given closure.

Source§

impl Updater

Source

pub fn update_transparent_with<F>(self, f: F) -> Result<Self, TransparentError>
where F: FnOnce(Updater<'_>) -> Result<(), UpdaterError>,

Available on crate feature transparent only.

Updates the transparent bundle with information in the given closure.

Source§

impl Updater

Source

pub fn new(pczt: Pczt) -> Self

Instantiates the Updater role with the given PCZT.

Source

pub fn update_global_with<F>(self, f: F) -> Self
where F: FnOnce(GlobalUpdater<'_>),

Updates the global transaction details with information in the given closure.

Source

pub fn set_sapling_anchor( self, anchor: Anchor, ) -> Result<Self, AnchorUpdateError>

Available on crate feature sapling only.

Sets the Sapling bundle anchor.

This may be called after shielded signatures have been added for transaction formats that do not commit shielded signatures to anchors. Sapling spend proofs depend on the anchor, so this must be called before proof creation for Sapling spends.

Returns an error if the PCZT’s transaction format does not support this update, if any Sapling spend proof is already present, or if the PCZT already contains a different Sapling anchor.

Source

pub fn set_orchard_anchor( self, anchor: Anchor, ) -> Result<Self, AnchorUpdateError>

Available on crate feature orchard only.

Sets the Orchard bundle anchor.

This may be called after shielded signatures have been added for transaction formats that do not commit shielded signatures to anchors. Orchard proofs depend on the anchor, so this must be called before proof creation.

Returns an error if the PCZT’s transaction format does not support this update, if an Orchard proof is already present, or if the PCZT already contains a different Orchard anchor.

Source

pub fn set_ironwood_anchor( self, anchor: Anchor, ) -> Result<Self, AnchorUpdateError>

Available on crate feature orchard only.

Sets the Ironwood bundle anchor.

This may be called after shielded signatures have been added for transaction formats that do not commit shielded signatures to anchors. Ironwood proofs depend on the anchor, so this must be called before proof creation.

Returns an error if the PCZT’s transaction format does not support this update, if an Ironwood proof is already present, or if the PCZT already contains a different Ironwood anchor.

Source

pub fn set_sapling_spend_witnesses( self, witnesses: impl IntoIterator<Item = (usize, MerklePath)>, ) -> Result<Self, SpendWitnessUpdateError>

Available on crate feature sapling only.

Sets spend witnesses for Sapling spends by spend index.

This may be called after shielded signatures have been added. Sapling spend proofs depend on the witnesses, so this must be called before proof creation for the updated spends.

Returns an error if any witness references a spend index that does not exist, or if a target spend proof is already present.

Source

pub fn set_orchard_spend_witnesses( self, witnesses: impl IntoIterator<Item = (usize, MerklePath)>, ) -> Result<Self, SpendWitnessUpdateError>

Available on crate feature orchard only.

Sets spend witnesses for Orchard actions by action index.

This may be called after shielded signatures have been added. Orchard proofs depend on the witnesses, so this must be called before proof creation.

Returns an error if any witness references an action index that does not exist, if the Orchard bundle is not using Orchard note plaintexts, or if an Orchard proof is already present.

Source

pub fn set_ironwood_spend_witnesses( self, witnesses: impl IntoIterator<Item = (usize, MerklePath)>, ) -> Result<Self, SpendWitnessUpdateError>

Available on crate feature orchard only.

Sets spend witnesses for Ironwood actions by action index.

This may be called after shielded signatures have been added. Ironwood proofs depend on the witnesses, so this must be called before proof creation.

Returns an error if any witness references an action index that does not exist, if the Ironwood bundle is not using Ironwood note plaintexts, or if an Ironwood proof is already present.

Source

pub fn finish(self) -> Pczt

Finishes the Updater role, returning the updated PCZT.
