Struct Output

pub struct Output { /* private fields */ }

Information about a Sapling output within a transaction.

Implementations

impl Output

pub fn cv(&self) -> &[u8; 32]

pub fn cmu(&self) -> &[u8; 32]

pub fn ephemeral_key(&self) -> &[u8; 32]

pub fn enc_ciphertext(&self) -> &Vec<u8>

The encrypted note plaintext for the output.

Encoded as a Vec<u8> because its length depends on the transaction version.

Once we have memo bundles, we will be able to set memos independently of Outputs. For now, the Constructor sets both at the same time.

pub fn out_ciphertext(&self) -> &Vec<u8>

The encrypted note plaintext for the output.

Encoded as a Vec<u8> because its length depends on the transaction version.

pub fn recipient(&self) -> &Option<[u8; 43]>

The raw encoding of the Sapling payment address that will receive the output.

• This is set by the Constructor.
• This is required by the Prover.

pub fn value(&self) -> &Option<u64>

The value of the output.

This may be used by Signers to verify that the value matches cv, and to confirm the values and change involved in the transaction.

This exposes the output value to all participants. For Signers who don’t need this information, or after signatures have been applied, this can be redacted.

pub fn rseed(&self) -> &Option<[u8; 32]>

The seed randomness for the output.

• This is set by the Constructor.
• This is required by the Prover, instead of disclosing shared_secret to them.

pub fn user_address(&self) -> &Option<String>

The user-facing address to which this output is being sent, if any.

• This is set by an Updater.
• Signers must parse this address (if present) and confirm that it contains recipient (either directly, or e.g. as a receiver within a Unified Address).

pub fn proprietary(&self) -> &BTreeMap<String, Vec<u8>>

Proprietary fields related to the note being spent.

Trait Implementations

impl Clone for Output

fn clone(&self) -> Output

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Output

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Output

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Output

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
