Trait OpPrecedence 

pub trait OpPrecedence {
    // Required method
    fn precedence(&self, writer: &dyn SqlWriter) -> i32;
}

Provides numeric precedence for expressions allowing sql writers to insert parentheses.

Required Methods

fn precedence(&self, writer: &dyn SqlWriter) -> i32

Lower numbers bind weaker, writers parenthesize when child precedence <= operator precedence.
