Struct CompactTx 

pub struct CompactTx {
    pub index: u64,
    pub hash: Vec<u8>,
    pub fee: u32,
    pub spends: Vec<CompactSaplingSpend>,
    pub outputs: Vec<CompactSaplingOutput>,
    pub actions: Vec<CompactOrchardAction>,
    pub ironwood_actions: Vec<CompactOrchardAction>,
}

A compact representation of the shielded data in a Zcash transaction.

CompactTx contains the minimum information for a wallet to know if this transaction is relevant to it (either pays to it or spends from it) via shielded elements only. This message will not encode a transparent-to-transparent transaction.

Fields

index: u64

Index and hash will allow the receiver to call out to chain explorers or other data structures to retrieve more information about this transaction.

the index within the full block

hash: Vec<u8>

the ID (hash) of this transaction, same as in block explorers

fee: u32

The transaction fee: present if server can provide. In the case of a stateless server and a transaction with transparent inputs, this will be unset because the calculation requires reference to prior transactions. If there are no transparent inputs, the fee will be calculable as: valueBalanceSapling + valueBalanceOrchard + valueBalanceIronwood

• sum(vPubNew) - sum(vPubOld) - sum(tOut)

spends: Vec<CompactSaplingSpend>

outputs: Vec<CompactSaplingOutput>

actions: Vec<CompactOrchardAction>

ironwood_actions: Vec<CompactOrchardAction>

Ironwood reuses the Orchard action encoding, so it reuses CompactOrchardAction. Fields 7 and 8 are vin and vout upstream; they are left free here.

Implementations

impl CompactTx

pub fn from_transaction( index: u64, hash: Hash, tx: &Transaction, nullifiers_only: bool, ) -> Self

Builds a CompactTx from a transaction, its precomputed mined transaction ID, and its index within its block.

If nullifiers_only is true, compact outputs are omitted and compact actions only contain nullifiers.

Trait Implementations

impl Clone for CompactTx

fn clone(&self) -> CompactTx

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

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

Inequality operator !=.

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.
