Enum Response 

Source 
pub enum Response {
    Block {
        tx_id: UnminedTxId,
        miner_fee: Option<Amount<NonNegative>>,
        sigops: u32,
    },
    Mempool {
        transaction: VerifiedUnminedTx,
        spent_mempool_outpoints: Vec<OutPoint>,
    },
}
Expand description

The response type for the transaction verifier service. Responses identify the transaction that was verified.

Variants§

§

Block

A response to a block transaction verification request.

Fields

§tx_id: UnminedTxId

The witnessed transaction ID for this transaction.

Response::Block responses can be uniquely identified by UnminedTxId::mined_id, because the block’s authorizing data root will be checked during contextual validation.

§miner_fee: Option<Amount<NonNegative>>

The miner fee for this transaction.

None for coinbase transactions.

§Consensus

The remaining value in the transparent transaction value pool of a coinbase transaction is destroyed.

https://zips.z.cash/protocol/protocol.pdf#transactions

§sigops: u32

The number of legacy signature operations in this transaction’s transparent inputs and outputs.

§

Mempool

A response to a mempool transaction verification request.

Fields

§transaction: VerifiedUnminedTx

The full content of the verified mempool transaction. Also contains the transaction fee and other associated fields.

Mempool transactions always have a transaction fee, because coinbase transactions are rejected from the mempool.

Response::Mempool responses are uniquely identified by the UnminedTxId variant for their transaction version.

§spent_mempool_outpoints: Vec<OutPoint>

A list of spent transparent::OutPoints that were found in the mempool’s list of created_outputs.

Used by the mempool to determine dependencies between transactions in the mempool and to avoid adding transactions with missing spends to its verified set.

Implementations§

Source§

impl Response

Source

pub fn tx_id(&self) -> UnminedTxId

The unmined transaction ID for the transaction in this response.

Source

pub fn miner_fee(&self) -> Option<Amount<NonNegative>>

The miner fee for the transaction in this response.

Coinbase transactions do not have a miner fee, and they don’t need UTXOs to calculate their value balance, because they don’t spend any inputs.

Source

pub fn sigops(&self) -> u32

The number of legacy transparent signature operations in this transaction’s inputs and outputs.

Source

pub fn is_mempool(&self) -> bool

Returns true if the request is a mempool request.
