    pub initial: Node<Option<Relation>>,
    pub extended: Vec<Node<Option<Relation>>>,
}

Logical And

Fields

initial: Node<Option<Relation>>

a singleton is a wrapper for a higher-priority node

extended: Vec<Node<Option<Relation>>>

additional elements represent a chained && computation

Trait Implementations

impl Clone for And

fn clone(&self) -> And

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for And

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

Formats the value using the given formatter.

impl Display for And

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

Formats the value using the given formatter.

impl PartialEq for And

fn eq(&self, other: &And) -> 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.
