Struct PoolFeeProtocolUpdate 

pub 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 values for each token. Uniswap V3 uses 4-bit denominators, while PancakeSwap V3 uses uint32 basis-point shares. 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: u32

The new token0 protocol-fee value.

fee_protocol1_new: u32

The new token1 protocol-fee value.

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: u32, fee_protocol1_new: u32, ts_event: UnixNanos, ts_init: UnixNanos, ) -> Self

Creates a new PoolFeeProtocolUpdate instance with the specified properties.

pub fn uniswap_v3_packed(&self) -> Option<u8>

Returns the new Uniswap V3 protocol-fee setting packed into a single byte.

The token0 denominator occupies the lower four bits and token1 the upper four bits. Returns None when either value does not fit the Uniswap V3 nibble layout.
