Module: binance/filters

Source: binance/filters.rs

Local validation for Binance exchangeInfo symbol filters.

This module deliberately consumes the exchange response instead of carrying a hand-maintained precision table. It currently understands the common PRICE_FILTER, LOT_SIZE, and MIN_NOTIONAL/NOTIONAL fields. Binance represents numeric fields as decimal strings; JSON numbers are accepted as a convenience for fixtures, but production callers should preserve the response unchanged.

A zero min/max bound is treated as disabled, matching Binance’s documented filter convention. Price and quantity normalization floors toward zero to the permitted increment: normalization never increases an order’s price or exposure. Callers must submit the returned values, not the original input.
