Struct Transaction 

pub struct Transaction {
    pub index: Option<TxIndex>,
    pub txid: Txid,
    pub version: TxVersionRaw,
    pub lock_time: RawLockTime,
    pub input: Vec<TxIn>,

    pub total_size: usize,
    pub weight: Weight,
    pub total_sigop_cost: SigOps,
    pub fee: Sats,

}

Transaction information compatible with mempool.space API format

Fields

index: Option<TxIndex>

Internal transaction index (brk-specific, not in mempool.space)

txid: Txid

Transaction ID

version: TxVersionRaw

Transaction version (raw i32 from Bitcoin protocol, may contain non-standard values in coinbase txs)

lock_time: RawLockTime

Transaction lock time

input: Vec<TxIn>

Transaction inputs

output: Vec<TxOut>

Transaction outputs

total_size: usize

Transaction size in bytes

weight: Weight

Transaction weight

total_sigop_cost: SigOps

Number of signature operations

fee: Sats

Transaction fee in satoshis

status: TxStatus

Confirmation status (confirmed, block height/hash/time)

Implementations

impl Transaction

pub fn fee(tx: &Transaction) -> Option<Sats>

pub fn compute_fee(&mut self)

pub fn encode_bytes(&self) -> Vec<u8>

Re-encode to canonical Bitcoin protocol bytes via bitcoin::Transaction. Lossless for mempool/confirmed txs (verified bytewise round-trip against Core over a 1000-tx live sample). Coinbase txs don’t round-trip because brk’s Vout is u16 while the protocol’s coinbase vout is 0xFFFFFFFF - callers that may see coinbase shouldn’t rely on this.

pub fn vsize(&self) -> VSize

Virtual size in vbytes (weight / 4, rounded up)

pub fn fee_rate(&self) -> FeeRate

Fee rate in sat/vB

pub fn refresh_sigops(&mut self)

Recompute total_sigop_cost from current inputs/outputs and write it back into the field. Cheaper than rebuilding the transaction when prevouts arrive; the only mutator paired with Self::total_sigop_cost.

pub fn total_sigop_cost(&self) -> SigOps

Total sigop cost (BIP-141 weight units).

Mirrors bitcoin::Transaction::total_sigop_cost, but reads prevouts from TxIn.prevout and uses bitcoin’s public Script::redeem_script (push-only check + last-push extraction in one). Inputs whose prevout is None skip the P2SH and witness components - legacy script-sig sigops are still counted.

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transaction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Transaction

fn deserialize<__D>( __deserializer: __D, ) -> Result<Transaction, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Transaction

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for Transaction

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
