impl<'a> Debug for RuleElement<'a>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a> Eq for RuleElement<'a>

impl<'a> Ord for RuleElement<'a>

fn cmp(&self, other: &RuleElement<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

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

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

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

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

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