Struct monero::blockdata::transaction::OwnedTxOut

pub struct OwnedTxOut<'a> {
    pub index: usize,
    pub out: &'a TxOut,
    pub sub_index: Index,
    pub tx_pubkey: PublicKey,
}

Transaction ouput that can be redeemed by a private key pair at a given index and are returned by the check_outputs method.

use monero::blockdata::transaction::Transaction;
use monero::consensus::encode::deserialize;
use monero::util::key::{KeyPair, PrivateKey, PublicKey, ViewPair};

// Keypair used to recover the ephemeral spend key of an output
let keypair = KeyPair {
    view: secret_view,
    spend: secret_spend,
};

// Viewpair used to scan a transaction to retreive owned outputs
let view_pair = ViewPair { view: secret_view, spend };

// Get all owned output for sub-addresses in range of 0-1 major index and 0-2 minor index
let owned_outputs = tx.prefix.check_outputs(&view_pair, 0..2, 0..3).unwrap();

for out in owned_outputs {
    // Recover the ephemeral private spend key
    let private_key = out.recover_key(&keypair);
}

Fields

index: usize

Index of the output in the transaction.

out: &'a TxOut

A reference to the actual redeemable output.

sub_index: Index

Index of the key pair to use, can be 0/0 for main address.

tx_pubkey: PublicKey

The associated transaction public key.

Implementations

impl<'a> OwnedTxOut<'a>

pub fn get_pubkeys(&self) -> Option<Vec<PublicKey>>

Retreive the public keys, if any.

pub fn recover_key(&self, keys: &KeyPair) -> PrivateKey

Recover the ephemeral private key for spending the output, this requires access to the private spend key.

Trait Implementations

impl<'a> Debug for OwnedTxOut<'a>

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

Formats the value using the given formatter.
