Function parse_daily_to_dataframe 

pub fn parse_daily_to_dataframe(
    path: impl AsRef<Path>,
    start_date_str: &str,
    end_date_str: &str,
) -> Result<DataFrame, DailyParseError>

按字符串日期范围解析日线文件为 DataFrame。

DataFrame 输出会额外补齐：

• suspendFlag
• preClose
• settlementPrice

Examples

use qmt_parser::parse_daily_to_dataframe;

let df = parse_daily_to_dataframe("data/day/000001.dat", "20230101", "20231231")?;
println!("{:?}", df.shape());
