Struct PoolFeeProtocolUpdate

    pub chain: SharedChain,
    pub dex: SharedDex,
    pub instrument_id: InstrumentId,
    pub pool_identifier: PoolIdentifier,
    pub block: u64,
    pub transaction_hash: String,

}

Represents a protocol-fee configuration change in a Uniswap V3-style pool.

Emitted by SetFeeProtocol, this carries the new protocol-fee denominators for each token. Only the new values are kept; the previous values in the event are not needed to rebuild state.

Fields

chain: SharedChain

The blockchain network where the protocol-fee change occurred.

dex: SharedDex

The decentralized exchange where the protocol-fee change occurred.

instrument_id: InstrumentId

The instrument ID for this pool’s trading pair.

pool_identifier: PoolIdentifier

The unique identifier for this pool (could be an address or other protocol-specific hex string).

block: u64

The blockchain block number where the protocol-fee change occurred.

transaction_hash: String

The unique hash identifier of the blockchain transaction containing the protocol-fee change.

transaction_index: u32

The index position of the transaction within the block.

log_index: u32

The index position of the protocol-fee change event log within the transaction.

fee_protocol0_new: u8

The new protocol-fee denominator for token0 (lower nibble of the packed fee_protocol).

fee_protocol1_new: u8

The new protocol-fee denominator for token1 (upper nibble of the packed fee_protocol).

ts_event: UnixNanos

UNIX timestamp (nanoseconds) when the protocol-fee change event occurred.

ts_init: UnixNanos

UNIX timestamp (nanoseconds) when the instance was created.

Implementations

impl PoolFeeProtocolUpdate

pub const fn new( chain: SharedChain, dex: SharedDex, instrument_id: InstrumentId, pool_identifier: PoolIdentifier, block: u64, transaction_hash: String, transaction_index: u32, log_index: u32, fee_protocol0_new: u8, fee_protocol1_new: u8, ts_event: UnixNanos, ts_init: UnixNanos, ) -> Self

Creates a new PoolFeeProtocolUpdate instance with the specified properties.

pub const fn packed(&self) -> u8

Returns the new protocol-fee setting packed into a single byte, matching slot0.feeProtocol.

The token0 denominator occupies the lower four bits and token1 the upper four bits.

Trait Implementations

impl Clone for PoolFeeProtocolUpdate

fn clone(&self) -> PoolFeeProtocolUpdate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PoolFeeProtocolUpdate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PoolFeeProtocolUpdate

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PoolFeeProtocolUpdate

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

Formats the value using the given formatter.

impl From<PoolFeeProtocolUpdate> for DefiData

fn from(value: PoolFeeProtocolUpdate) -> Self

Converts to this type from the input type.

impl HasTsInit for PoolFeeProtocolUpdate

fn ts_init(&self) -> UnixNanos

Returns the UNIX timestamp (nanoseconds) when the instance was created.

impl PartialEq for PoolFeeProtocolUpdate

fn eq(&self, other: &PoolFeeProtocolUpdate) -> 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 Serialize for PoolFeeProtocolUpdate

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
