Struct monero::blockdata::transaction::TransactionPrefix

pub struct TransactionPrefix {
    pub version: VarInt,
    pub unlock_time: VarInt,
    pub inputs: Vec<TxIn>,
    pub outputs: Vec<TxOut>,
    pub extra: ExtraField,
}

The part of the transaction that contains all the data except signatures.

As transaction prefix implements hash::Hashable it is possible to generate the transaction prefix hash with tx_prefix.hash().

Fields

version: VarInt

Transaction format version.

unlock_time: VarInt

The transaction can not be spend until after a certain number of blocks, or until a certain time.

inputs: Vec<TxIn>

Array of inputs.

outputs: Vec<TxOut>

Array of outputs.

extra: ExtraField

Additional data associated with a transaction.

Implementations

impl TransactionPrefix

pub fn nb_inputs(&self) -> usize

Return the number of transaction’s inputs.

pub fn nb_outputs(&self) -> usize

Return the number of transaction’s outputs.

pub fn tx_pubkey(&self) -> Option<PublicKey>

Return the transaction public key present in extra field.

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

Return the additional public keys present in extra field.

pub fn check_outputs(
    &self,
    pair: &ViewPair,
    major: Range<u32>,
    minor: Range<u32>
) -> Result<Vec<OwnedTxOut<'_>>, Error>

Iterate over transaction outputs and find outputs related to view pair.
