Trait Implementations

impl Clone for Parenthetical

fn clone(&self) -> Parenthetical

Returns a copy of the value.

impl From<Parenthetical> for Condition

fn from(condition: Parenthetical) -> Self

Converts to this type from the input type.

impl<T> From<T> for Parenthetical

where T: Into<Box<Condition>>,

fn from(condition: T) -> Self

Converts to this type from the input type.

impl PartialEq for Parenthetical

fn eq(&self, other: &Parenthetical) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
