Struct ChangeAddressGenerator 

pub struct ChangeAddressGenerator { /* private fields */ }

Change address generator for Silent Payments.

When sending a Silent Payment, the sender may need to create a change output back to themselves. This module provides utilities for generating deterministic change addresses.

Implementations

impl ChangeAddressGenerator

pub fn new( scan_privkey: &[u8; 32], spend_privkey: &[u8; 32], network: Network, ) -> Result<Self>

Create a new change address generator.

pub fn address(&self) -> Result<SilentPaymentAddress>

Get the Silent Payment address for this wallet.

pub fn generate_change( &self, outpoints: &[([u8; 32], u32)], index: u32, ) -> Result<([u8; 32], [u8; 32])>

Generate a change output key for a transaction.

Arguments

• outpoints - (txid, vout) pairs for all inputs
• index - Change output index (for multiple change outputs)

Returns

(output_pubkey, spending_key) tuple

pub fn is_change_output( &self, output_pk: &[u8; 32], outpoints: &[([u8; 32], u32)], max_index: u32, ) -> Result<Option<(u32, [u8; 32])>>

Check if an output is a change output from this wallet.
