Enum JournalDecision 

pub enum JournalDecision {
    Keep,
    Elide,
    Recompute,
}

What the recorder should do with a Journaled write’s tape entry.

Variants

Keep

Journal the destroyed value — the reverse executor will read it back.

Elide

Skip the entry: the destroyed value is program-invisible scratch that no reverse step reads.

Recompute

(Adiabatic, P3) Skip the entry; recompute the value on reverse from its pure defining segment.

Trait Implementations

impl Clone for JournalDecision

fn clone(&self) -> JournalDecision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JournalDecision

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

Formats the value using the given formatter.

impl PartialEq for JournalDecision

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