以下是一个使用 calamine 库读取Excel文件的简单示例: rust use calamine::{open_workbook, reader, xlsx}; use std::fs::File; use std::io::Read; fn main() -> Result<(), Box<dyn std::error::Error>> { // 打开Excel文件 let mut file = File::open("example.xlsx")?
要在Rust中解析Excel文件,可以使用`xlsxwriter`库。以下是一个简单的示例: 1. 首先,在`Cargo.toml`文件中添加依赖: ```toml [dependencies] xlsxwriter = "0.7.0" ``` 2. 然后,编写以下代码来读取和解析Excel文件: ```rust use xlsxwriter::Workbook; use std::fs::File; use std::io::Read; fn ...
