structs-from-excel

此crate添加了一个过程宏，该宏可以根据给定的Excel电子表格生成struct。这是为项目制作的，其中我知道其中一个帮助的人不希望与JSON或XML或任何合理的事情一起工作。对不起。

宏的调用方法如下

use structs_from_excel;

#[sheet("resources/objects.xls")]
pub struct Object; // This struct will get ignored and replaced by whatever structs you define. Anything can go here, pretty much.

然后读取并解析每个电子表格，注意以下规则

• 第一行的第一个单元格应称为name。
• 第一行每个后续单元格的名称都用作每个struct的名称。
• 第一行后续的单元格用于字段名称。

以下两个电子表格

变为

    enum StructsFromExcel {
        Slime(Slime),
        OtherSlime(OtherSlime),
        PlayerOne(PlayerOne),
        PlayerTwo(PlayerTwo),
        PlayerThree(PlayerThree),
        PlayerFour(PlayerFour),
