Motivation

See issues:

Implements issue #28 (GET /v1/trades/tx/{tx_hash}) from the v1 route handlers tracking issue. This endpoint retrieves all trades associated with a given transaction hash, including per-trade IO ratios and aggregate totals.

Solution

  • Restructured the trades module from a single file into a directory with get_by_tx and get_by_address submodules for better separation of concerns
  • Implemented the full get_trades_by_tx handler that queries all configured orderbook subgraphs for trades matching a transaction hash, fetches associated order data for owner addresses, and computes per-trade and aggregate IO ratios using rain-math-float
  • Added a NotYetIndexed error variant (ApiError::NotYetIndexed) returning 202 Accepted when the subgraph hasn't indexed the transaction yet
  • Updated the rain.orderbook submodule to include get_trades_for_transaction support and subgraph fixes
  • Introduced a TradesTxDataSource trait for testability, with comprehensive unit tests using mock data sources
  • Added futures crate for concurrent order lookups

fix #28

… fix

Includes get_trades_for_transaction with polling, pub order_operations,
and fix for nested transaction filter in SgTransactionTradesQuery.
Maps to HTTP 202 with code NOT_YET_INDEXED, logged at info level
since it represents an expected transient state during indexing.
Queries all configured orderbooks for trades in a transaction, looks up
order owners by hash, computes IO ratios and totals using Float math.
Distinguishes 404 (no trades) vs 202 (not yet indexed).

Converts trades.rs to module directory with get_by_tx and get_by_address
sub-modules following the swap module pattern.
