}

Field mapping configuration for parsing venue API responses.

All fields are optional; omitting a field means the venue doesn’t provide that data (the corresponding Rust Option will be None).

Fields

asks_key: Option<String>

JSON key for the asks array.

bids_key: Option<String>

JSON key for the bids array.

level_format: Option<String>

Level format: "positional" (default) for [price, qty] arrays, "object" for {price: x, size: y} objects.

level_price_field: Option<String>

Field name for price when level_format is "object".

level_size_field: Option<String>

Field name for size/quantity when level_format is "object".

last_price: Option<String>

high_24h: Option<String>

low_24h: Option<String>

volume_24h: Option<String>

quote_volume_24h: Option<String>

best_bid: Option<String>

best_ask: Option<String>

items_key: Option<String>

JSON key holding the array of items. Empty or omitted = root is the array.

filter: Option<FilterConfig>

Filter configuration for endpoints that return data for all pairs.

price: Option<String>

Field mappings for individual trade items.

quantity: Option<String>

quote_quantity: Option<String>

timestamp_ms: Option<String>

id: Option<String>

side: Option<SideMapping>

ohlc_format: Option<String>

Response format: "array_of_arrays" (e.g., Binance) or "objects" (default). When "array_of_arrays", each candle is a positional array and the ohlc_fields list determines field order.

ohlc_fields: Option<Vec<String>>

Ordered field names for array-of-arrays format. Default: ["open_time", "open", "high", "low", "close", "volume", "close_time"].

open_time: Option<String>

open: Option<String>

high: Option<String>

low: Option<String>

close: Option<String>

ohlc_volume: Option<String>

Base volume field name (for OHLC). Falls back to volume_24h if absent.

close_time: Option<String>
