Enum Connective 

pub enum Connective {
    And,
    Or,
    Implies,
    Iff,
    Not,
}

Trait for formatting logical expressions in various notations. The connectives a formula joins its parts with, whatever token the parser read each from: If, Then and Implies are all the implication. Every printer asks this one mapping, so the Logic Output, the Syntax Tree and the generated Rust can never draw a connective differently.

Trait Implementations

impl Clone for Connective

fn clone(&self) -> Connective

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Connective

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

Formats the value using the given formatter.

impl PartialEq for Connective

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

Tests for self and other values to be equal, and is used by ==.

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

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