Struct monero::blockdata::transaction::OwnedTxOut

pub struct OwnedTxOut<'a> { /* private fields */ }

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.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);
}

Implementations

impl<'a> OwnedTxOut<'a>

pub fn index(&self) -> usize

Returns the index of this output in the transaction

pub fn out(&self) -> &'a TxOut

Returns a reference to the actual redeemable output.

pub fn sub_index(&self) -> Index

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

pub fn tx_pubkey(&self) -> PublicKey

Returns the associated transaction public key.

pub fn amount(&self) -> Option<Amount>

Returns the unblinded or clear amount of this output.

None if we didn’t have enough information to unblind the output.

pub fn blinding_factor(&self) -> Option<Scalar>

Returns the original blinding factor of this output.

None if we didn’t have enough information to unblind the output.

pub fn commitment(&self) -> Option<EdwardsPoint>

Returns the original commitment of this output.

None if we didn’t have enough information to unblind the output.

pub fn 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.
