介绍一款Rust读取excel文件的库

Rust是一款新型的、主打安全的语言。但是，百度上搜索读取excel的库还很难找。不过，我找到了一款，推荐给大家：ooxml, 当前版本0.2.7.

这是依赖：

[dependencies]
ooxml = "0.2.7"
itertools = "0.11.0"

具体代码如下：

use ooxml::document::SpreadsheetDocument;

fn main() {

    let filename = "F:/programWorks/Java/demo4cupdata/demoB.xlsx";
    let xlsx =
        SpreadsheetDocument::open(filename).unwrap();

    let workbook = xlsx.get_workbook();
    // println!("我能自己输出点什么吗？{:?}", xlsx);

    let sheet_names = workbook.worksheet_names();
    println!("包含：");
    for name in sheet_names {
        println!("{}", name);
    }

    for (sheet_idx, sheet) in workbook.worksheets().iter().enumerate() {
        println!("worksheet {}", sheet_idx);
        println!("worksheet dimension: {:?}", sheet.dimenstion());
        println!("---------DATA---------");
        for rows in sheet.rows() {
            // get cell values
            let cols: Vec<_> = rows
                .into_iter()
                .map(|cell| cell.value().unwrap_or_default())
                .collect();
            println!("{}", itertools::join(&cols, ","));

            for cell in cols {
                println!("{}", cell);
            }
        }
    }
}

亲测可用。
