rust的nutyp验证和validator验证数据的方法示例详解

nutype = { version = "0.5.0", features = ["serde","regex"] }
regex = "1"
thiserror = "1"

#[nutype(
sanitize(trim, lowercase),
validate(not_empty, len_char_min = 3, len_char_max = 30),
derive(asref, clone, debug, serialize, deserialize, partialeq)
)]
// asref表示可以单独访问username，clone复制
pub struct username(string);
// #[nutype(
// validate(not_empty, len_char_min = 8),
// derive(asref, clone, serialize, deserialize, partialeq)
// )]
#[nutype(validate(with = password_regex, error = errormessage),derive(debug, partialeq),)]
pub struct password(string);
// 正则匹配手机号
static phone_number_regex: lazylock<regex> = lazylock::new(||
regex::new("^(13[0-9]|14[01456879]|15[0-35-9]|16[2567]|17[0-8]|18[0-9]|19[0-35-9])\\d{8}$"
).unwrap());
// 直接使用正则表达式
#[nutype(validate(regex = phone_number_regex))]
pub struct phonenumber(string);
// 自定义方法
#[nutype(validate(with = email_regex, error = errormessage))]
pub struct emailnumber(string);
// 正则匹配邮箱号
static email_number_regex: lazylock<regex> = lazylock::new(||
regex::new("^\\w+([-+.]\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*$"
).unwrap());
pub fn email_regex(name: &str) -> result<(), errormessage> {
	match email_number_regex.captures(name){
		// 这里可以返回自定义的错误类型
		none => err(errormessage::invalidemailformat),
		some(_) => ok(())
	}
}

validator = {version = "0.18.1",features = ["derive"]}
lazy_static = "1.5.0"

#[derive(validate, debug, default, clone, serialize, deserialize)]
pub struct registeruserdto {
#[validate(length(min = 1, message = "姓名为必填项"))]
pub name: string,
#[validate(length(min = 0, message = "用户名不是必填项"))]
pub username: string,
#[validate(
length(min = 1, message = "电子邮件是必需的"),
email(message = "电子邮件无效")
)]
pub email: string,
#[validate(
length(min = 1, message = "手机号是必需的"),
)]
pub phone: string,
#[validate(
length(min = 6, message = "密码必须至少为 6 个字符")
)]
pub password: string,
#[validate(
length(min = 1, message = "需要确认密码"),
must_match(other = "password", message="密码不匹配")
)]
#[serde(rename = "passwordconfirm")]
pub password_confirm: string,
}
//validator自定义方法是无法使用自定义错误类型的，必须使用crate的，具体看validator crate
