create request params included option

[fan-tastic-z]

If option parameters are included in the request parameters, is it possible to include practice for this case in the sample code

example:

#[derive(Debug, Clone, Deserialize)]
pub struct CreateUserHttpRequestBody {
    name: String,
    password: String,
    email: Option<String>,
    phone: Option<String>,
    start_time: DateTime<FixedOffset>,
    end_time: DateTime<FixedOffset>,
    remark: Option<String>,
}
