Struct brane_ctl::wizard::validator::FromStrValidator

pub struct FromStrValidator<T>
where
    T: FromStr,
{
    pub field_name: &'static str,
    /* private fields */
}

The validator is a wrapper for all types that implement std::str::FromStr, it uses FromStr to validate if the provided input is correct. This assumes that the Result that FromStr provides correctly distinguishes correct from incorrect inputs. If your FromStr implementation is expensive, this might come at a performance hit.

Fields

field_name: &'static str
