Struct CustomResultRule 

pub struct CustomResultRule<T: ?Sized, F>
where
    F: Fn(&T, &ValidationContext) -> ValidationResult<()> + Send + Sync,
{
    pub rule_name: String,
    pub validator: Arc<F>,
    /* private fields */
}

Custom validation with result - allows returning detailed errors.

Fields

rule_name: String

Rule name for error reporting

validator: Arc<F>

The validation function
