Struct FallbackPoolIndex 

pub struct FallbackPoolIndex { /* private fields */ }

Fallback pools by token pair and fee tier, so finding one is a lookup, not a market scan.

A pool qualifies on its component alone — protocol system, token pair and fee attribute — so the index only changes when the market adds or removes a component, not when a pool’s state changes. apply_event keeps it current from MarketEvent::MarketUpdated, which costs one lookup per added component instead of a full rebuild.

Implementations

impl FallbackPoolIndex

pub fn build(market: &MarketDataView<'_>) -> Self

Indexes every qualifying component in the market. Call once, then keep current with apply_event.

pub fn apply_event(&mut self, market: &MarketDataView<'_>, event: &MarketEvent)

Adds the components in event and drops the removed ones.

updated_components are state changes, which cannot alter whether a component qualifies, so they are ignored.

pub fn pool_for( &self, token_a: &Address, token_b: &Address, fee_tier: u32, ) -> Option<&ComponentId>

The component the router would fall back to.
