TransparentSpendPolicy

zcash_client_backend::data_api::wallet::input_selection

Struct TransparentSpendPolicy 

Source 
pub struct TransparentSpendPolicy { /* private fields */ }
Available on crate feature transparent-inputs only.
Expand description

Specifies how transparent UTXOs may be spent in a transfer, when a SpendPolicy permits transparent spending.

Spending transparent funds links the chosen transparent addresses on-chain, reducing privacy, so a caller opts in by attaching this to a SpendPolicy via SpendPolicy::with_transparent (the absence of a policy — the default — spends no transparent UTXOs). The policy names the TransparentSource the UTXOs may be drawn from and, via CoinbasePolicy, whether coinbase or non-coinbase outputs are spent.

Implementations§

Source§

impl TransparentSpendPolicy

Source

pub fn any_account_addr() -> Self

Spends non-coinbase UTXOs from arbitrary transparent receivers belonging to the account, as needed to satisfy the request. The proposer chooses the addresses, potentially linking them. (The legacy ANY_TADDR behavior.)

Source

pub fn from_addresses(taddrs: NonEmpty<TransparentAddress>) -> Self

Spends non-coinbase UTXOs only from the specified transparent addresses, intentionally linking them.

Source

pub fn from_one_address(taddr: TransparentAddress) -> Self

Spends non-coinbase UTXOs only from a single transparent address.

Source

pub fn with_coinbase(self, coinbase: CoinbasePolicy) -> Self

Returns a copy of this policy with the given coinbase policy in effect.

Source

pub fn source(&self) -> &TransparentSource

Returns the transparent source from which UTXOs may be drawn.

Source

pub fn coinbase(&self) -> CoinbasePolicy

Returns the coinbase policy in effect for this transparent spend.
