Enum ReferenceValue 

pub enum ReferenceValue {
    Original {
        parent: Parent,
        stale: bool,
    },
    Null,
}

What a reference reads as in the app’s table. Substitution changes neither its winning write nor its timestamp; lost values stay as written (§9.1).

Variants

Original

The original parent; stale references take their children out.

Fields

parent: Parent

The original parent and generation.

stale: bool

The parent’s carried generation has been deleted since.

Null

A set-null reference whose parent’s generation was deleted.

Trait Implementations

impl Clone for ReferenceValue

fn clone(&self) -> ReferenceValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReferenceValue

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

Formats the value using the given formatter.

impl PartialEq for ReferenceValue

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