Struct StockPool 

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

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

impl<T: Default> StockPool<T>

pub fn new_default() -> StockPool<T>

impl<T> StockPool<T>

pub fn new_empty() -> StockPool<T>

pub fn len(&self) -> usize

pub fn all_items(&self) -> Vec<&T>

pub fn is_empty(&self, i7: i32) -> bool

pub fn get(&self, i7: i32) -> Option<&T>

获取股票数据; 股票代码是7位数字, 1开头说明是上海票, 2开头说明是深圳票; 其它6位数与常规股票代码一样;

pub fn get_unchecked(&self, i7: i32) -> &T

pub fn get_mut(&self, i7: i32) -> Option<&mut T>

pub fn insert(&self, i7: i32, val: T) -> Option<Box<T>>
