Trait Fielder 

pub trait Fielder {
    // Required methods
    fn visit_bool(&mut self, b: bool);
    fn visit_float(&mut self, f: f64);
    fn visit_int(&mut self, i: i64);
    fn visit_string(&mut self, s: &str);
    fn visit_null(&mut self);
}

A field visitor that may be implemented to iterate and visit all the elements of a Row.

Required Methods

fn visit_bool(&mut self, b: bool)

Called for fields of type bool with the value of the field

fn visit_float(&mut self, f: f64)

Called for fields of type float with the value of the field

fn visit_int(&mut self, i: i64)

Called for fields of type int with the value of the field

fn visit_string(&mut self, s: &str)

Called for fields of type String with the value of the field

fn visit_null(&mut self)

Called for fields where the value of the field is missing. This method may be as simple as doing nothing but there are use cases where some operations are required.
