Trait form_checker::FieldType

pub trait FieldType {
    fn from_str(
        &self, 
        field_name: &str, 
        field_title: &str, 
        value: &str
    ) -> Result<FieldValue, Message>;
}

This trait represents the field type.

We offer some field types, like Str, I64, ChinaMobile and Email.

You just need to implement this trait to transform the raw str value into a FeildValue.

field_name is the field name in the form.

field_title is a descriptive value, used to diplay invalid messages.

value is the raw str value from the form.

And of course you can implement your own field type!
