Daniel Savu f4626eb4fe Allow protocol-specific indexing (#3544) ... ### Description - Generalizes contract syncer hashmaps to store trait objects instead of concrete structs, since both `SequencedDataContractSync` and `WatermarkContractSync` implement `ContractSyncer` - The nice thing this enables is being able to instantiate a different type of syncer for the same contract, for different chain protocols (e.g. for IGP, we can use a sequenced syncer on sealevel and cosmwasm, and a watermark syncer on EVM). - The problem is that `ContractSyncer` is implemented on different trait bounds on `SequencedDataContractSync` and `WatermarkContractSync`. Most notably, the `SequencedDataContractSync` impl bounds the indexed type by the `Sequenced` trait. This means that if a type is to be indexed by more than one syncer strategy, it needs to implement the union of bounds of those strategies - **Blocker:** In the IGP, this means that `InterchainGasPayment` needs to implement `Sequenced` and we have no obvious way of getting that just from the type. Even if the sequence is derived from the type, it has to be a sensible value, since indexing reliability depends on it. - Similar to the point above, we now have `contract_syncs`, a single function that instantiates contract syncs for all chains. Since `contract_syncs` must be able to build a `ContractSyncer` trait obj for all syncer types, it bounds both `T` (the indexed type) and `D` (the log store type) with a union of bounds, so it may be too strict for some types in the future. - The scraper now uses forward-backward indexing instead of just forward indexing, because that simplified the refactor - there's now a convenience trait called `TryFromWithMetrics` that allows adding this bound: `SequenceIndexer<T>: TryFromWithMetrics<ChainConf>,`. This isn't really extendable if we use non-sequence indexers, but it's fine for now since this is used everywhere - replaces the macro-based contract syncer builder with generic fns Still todo: - add new `IndexingDecorator<T>` struct that can wrap `InterchainGasPayment`, so we can use sequence-aware indexing for the IGP - remove sequence logic from the watermark cursor ### Drive-by changes <!-- Are there any minor or drive-by changes also included? --> ### Related issues <!-- - Fixes #[issue number here] --> ### Backward compatibility <!-- Are these changes backward compatible?
