DYN-PRODUCT

一个创建运行时确定大小的笛卡尔积的crate。
如果大小在编译时确定，则最好使用 itertools::iproduct!。

用法

将依赖项添加到您的 Cargo.toml。

[dependencies]
dyn-product = "0.1"

示例

use dyn_product::DynProduct;

let data = vec![
    vec!["GroupA-1", "GroupA-2", "GroupA-3"],
    vec!["GroupB-1", "GroupB-2"],
    vec!["GroupC-1", "GroupC-2", "GroupC-3", "GroupC-4"],
];

for item in DynProduct::from(&data) {
    println!("{:?}", item);
}

输出
