- Replace instance-based EventParser with static method design
- Introduce ParserCache module for protocol config caching
- Simplify EventProcessor to pure functional handlers
- Optimize metrics: remove min/max tracking, keep last + avg only
- Reduce atomic operations in hot path for better performance
- Convert UnifiedEvent from trait object (Box<dyn UnifiedEvent>) to concrete enum type
- Remove match_event! macro in favor of native match expressions
- Simplify event metadata access: event.event_type() -> event.metadata().event_type
- Unify event callback signatures: Fn(Box<dyn UnifiedEvent>) -> Fn(UnifiedEvent)
- Update all example code to use the new enum-based event system
- Optimize type system to reduce runtime overhead and improve type safety
Affected scope:
- Core event parser and processor
- All protocol event definitions (PumpFun, PumpSwap, Bonk, Raydium series, etc.)
- gRPC and Shred streaming modules
- All example code
- Add requires_inner_instruction field to GenericEventParseConfig
- Skip events that require but lack inner instruction data during processing
- Set PumpFun migrate events to require inner instructions (prevents parsing failed migrations)
- Improve borsh deserialization safety across all protocol decoders
- Add MarketState support for raydium_amm_v4
- Prevent buffer overflow in data decoding operations
- Add account event parser (account_event_parser.rs) for account-level event handling
- Introduce type definitions for pumpfun, pumpswap, raydium_amm_v4, raydium_clmm, raydium_cpmm protocols
- Enhance event processor to support account event processing alongside transactions
- Improve subscription system with separate transaction and account filters
- Optimize parser configuration using Option types for cleaner code structure
- Update examples and documentation to reflect new capabilities
Changes include:
- 6 new types.rs files for protocol-specific data structures
- Updated event processor for account, transaction, and block meta events
- Refactored subscription manager with account filtering support
- Enhanced metrics and batch processing logic
- Refactor streaming architecture with modular grpc components
- Add batch processing system with backpressure strategies
- Implement performance monitoring and metrics collection
- Add multi-protocol parser with block metadata support
- Enhance configuration system with preset profiles
- Add parse_tx_events example and update documentation
- Optimize yellowstone_grpc client complexity
- Bump version to 0.1.11
- Upgrade Solana deps to 2.3.x, yellowstone-grpc to 8.0.0
- Fix inner instruction indexing and timestamp handling
- Improve PumpFun/PumpSwap parser program ID support
- Bump version from 0.1.7 to 0.1.8
- Update version references in README.md and README_CN.md
- Add global_volume_accumulator and user_volume_accumulator fields to PumpFunTradeEvent
- Fix account index mapping in trade parser (creator_vault index adjusted from 8 to 9)
This update introduces volume accumulator support for PumpFun protocol event parsing,
aligning with the latest protocol account structure changes.
This update includes the following improvements:
- Version upgraded to 0.1.5
- Added subscribe_events_v2 API with more granular account filtering
- Marked original subscribe_events API as deprecated
- Fixed bug
