简单的写了个 Rust 结构体字段验证过程宏

自己这两天边学边写，搞了个简单的验证器过程宏，

用在 web 框架里面可以比较方便的验证前端传来的各个字段

github 地址：https://github.com/horou-dsk/fields-valid.git

刚学过程宏，写的很简陋，内置的功能不多

有大佬觉得写的不好的话，还望指点迷津

示例：

use fields_valid::FieldsValidate; #[derive(FieldsValidate)] struct User { // #[valid(len(5, 11), email, regex("^[\\d@\\.]+$"), "邮箱格式不正确")] #[valid(len(5, 17), "The length of the mailbox must be between 5-16")] #[valid(email, "E-mail format is incorrect")] email: String, #[valid(len(8, 17), "The minimum password length is 8 digits and the maximum is 16 digits")] password: String, #[valid(eq("#password"), "The two passwords are inconsistent")] password2: String, #[valid(len(5, 12), "The length of the phone number is incorrect")] #[valid(regex("\\d+"), "The phone number must be a number")] phone: Option<String>, #[valid(range(5.8, 10.1), "Incorrect amount returned")] amount: u32, } #[inline] fn fields_validate<T: FieldsValidate>(fields: &T) -> Result<(), &'static str> { fields.fields_validate() } fn main() { let user = User { email: "[email protected]".to_string(), password: "12ndd232.23".to_string(), password2: "1225".to_string(), phone: None, //Some("111111".to_string()) amount: 7, }; println!("{:?}", fields_validate(&user)); }
