Struct Derived 

pub struct Derived {
    pub atom: String,
    pub value: Value,
    pub origin: Origin,
}

A fact produced by a RULE during forward chaining.

Fields

atom: String

Human label of the atom whose value was derived.

value: Value

The value the rule assigned (TRUE, or FALSE for a THEN NOT …).

origin: Origin

Provenance of the RULE that produced it.

Trait Implementations

impl Clone for Derived

fn clone(&self) -> Derived

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Derived

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

Formats the value using the given formatter.

impl Eq for Derived

impl PartialEq for Derived

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