fn lt(&self, other: &Literal<'a>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Literal<'a>) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Literal<'a>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Literal<'a>) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
