Struct StockPool 

pub struct StockPool<T> { /* private fields */ }

Design a high-performance stock pool, where all data is stored in arrays, and data is accessed via array indices; this index is converted from the stock code; 4 arrays, one for Shanghai Main Board stocks, one for Shenzhen Main Board stocks, one for ChiNext stocks; and one for STAR Market stocks; The length of each array is fixed, determined by the number of stocks in the A-share market; for example, if the number of Shanghai Main Board stocks is 1500, the array length is 1500;

设计一个高性能股票池, 数据全部以数组的形式存储, 通过数组的下标来获取数据; 此下标是股票代码转换而来; 4个数组, 一个存储上海主板股票, 一个存储深圳主板股票, 一个存储创业板股票; 还有一个数组存储科创板股票; 每个数组的长度是固定的, 都根据A股市场的股票数量来确定; 例如上海主板股票数量是1500, 则数组的长度是1500;

Implementations
