Struct TransactionTemplate 

pub struct TransactionTemplate<FeeConstraint>
where
    FeeConstraint: Constraint + Clone + Copy,
{
    pub(crate) data: SerializedTransaction,
    pub(crate) hash: Hash,
    pub(crate) auth_digest: AuthDigest,
    pub(crate) depends: Vec<u16>,
    pub(crate) fee: Amount<FeeConstraint>,
    pub(crate) sigops: u32,
    pub(crate) required: bool,
}

Transaction data and fields needed to generate blocks using the getblocktemplate RPC.

Fields

data: SerializedTransaction

The hex-encoded serialized data for this transaction.

hash: Hash

The transaction ID of this transaction.

auth_digest: AuthDigest

The authorizing data digest of a v5 transaction, or a placeholder for older versions.

depends: Vec<u16>

The transactions in this block template that this transaction depends upon. These are 1-based indexes in the transactions list.

Zebra’s mempool does not support transaction dependencies, so this list is always empty.

We use u16 because 2 MB blocks are limited to around 39,000 transactions.

fee: Amount<FeeConstraint>

The fee for this transaction.

Non-coinbase transactions must be NonNegative. The Coinbase transaction fee is the negative sum of the fees of the transactions in the block, so their fee must be NegativeOrZero.

sigops: u32

The number of transparent signature operations in this transaction.

required: bool

Is this transaction required in the block?

Coinbase transactions are required, all other transactions are not.

Implementations

impl<FeeConstraint> TransactionTemplate<FeeConstraint>

where FeeConstraint: Constraint + Clone + Copy,

Auto-generated by derive_getters::Getters.

pub fn data(&self) -> &SerializedTransaction

The hex-encoded serialized data for this transaction.

pub fn hash(&self) -> Hash

The transaction ID of this transaction.

pub fn auth_digest(&self) -> AuthDigest

The authorizing data digest of a v5 transaction, or a placeholder for older versions.

pub fn depends(&self) -> &Vec<u16>

The transactions in this block template that this transaction depends upon. These are 1-based indexes in the transactions list.

Zebra’s mempool does not support transaction dependencies, so this list is always empty.

We use u16 because 2 MB blocks are limited to around 39,000 transactions.

pub fn fee(&self) -> Amount<FeeConstraint>

The fee for this transaction.

Non-coinbase transactions must be NonNegative. The Coinbase transaction fee is the negative sum of the fees of the transactions in the block, so their fee must be NegativeOrZero.

pub fn sigops(&self) -> u32

The number of transparent signature operations in this transaction.

pub fn required(&self) -> bool

Is this transaction required in the block?

Coinbase transactions are required, all other transactions are not.

impl<FeeConstraint> TransactionTemplate<FeeConstraint>

where FeeConstraint: Constraint + Clone + Copy,

pub fn new( data: SerializedTransaction, hash: Hash, auth_digest: AuthDigest, depends: Vec<u16>, fee: Amount<FeeConstraint>, sigops: u32, required: bool, ) -> Self

Constructs a new TransactionTemplate.

impl TransactionTemplate<NegativeOrZero>

pub fn from_coinbase(tx: &UnminedTx, miner_fee: Amount<NonNegative>) -> Self

Convert from a generated coinbase transaction into a coinbase transaction template.

miner_fee is the total miner fees for the block, excluding newly created block rewards.

Trait Implementations

impl<FeeConstraint> Clone for TransactionTemplate<FeeConstraint>

where FeeConstraint: Constraint + Clone + Copy + Clone,

fn clone(&self) -> TransactionTemplate<FeeConstraint>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<FeeConstraint> Debug for TransactionTemplate<FeeConstraint>

where FeeConstraint: Constraint + Clone + Copy + Debug,

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

Formats the value using the given formatter.

impl<'de, FeeConstraint> Deserialize<'de> for TransactionTemplate<FeeConstraint>

where FeeConstraint: Constraint + Clone + Copy,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&VerifiedUnminedTx> for TransactionTemplate<NonNegative>

fn from(tx: &VerifiedUnminedTx) -> Self

Converts to this type from the input type.

impl From<VerifiedUnminedTx> for TransactionTemplate<NonNegative>

fn from(tx: VerifiedUnminedTx) -> Self

Converts to this type from the input type.

impl<FeeConstraint> PartialEq for TransactionTemplate<FeeConstraint>

where FeeConstraint: Constraint + Clone + Copy + PartialEq,

fn eq(&self, other: &TransactionTemplate<FeeConstraint>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<FeeConstraint> Serialize for TransactionTemplate<FeeConstraint>

where FeeConstraint: Constraint + Clone + Copy,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<FeeConstraint> Eq for TransactionTemplate<FeeConstraint>

where FeeConstraint: Constraint + Clone + Copy + Eq,

impl<FeeConstraint> StructuralPartialEq for TransactionTemplate<FeeConstraint>

where FeeConstraint: Constraint + Clone + Copy,

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
