Enum TemporalOperator 

pub enum TemporalOperator {
    Past,
    Future,
}

Prior-style tense logic operators.

Based on Arthur Prior’s tense logic where P (“it was the case that”) and F (“it will be the case that”) are modal operators over time.

Variants

Past

Past tense: P(φ) — “it was the case that φ”.

Future

Future tense: F(φ) — “it will be the case that φ”.

Trait Implementations

impl Clone for TemporalOperator

fn clone(&self) -> TemporalOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TemporalOperator

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

Formats the value using the given formatter.

impl PartialEq for TemporalOperator

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