Struct ColumnValue 

pub struct ColumnValue<V> {
    pub value: V,
    pub parents: BTreeMap<ForeignKey, Parent>,
}

A column’s value and the parent generations recorded with it. The metadata follows the winning setter, including for values kept as lost.

Fields

value: V

The app’s value; the merge does not interpret SQL values.

parents: BTreeMap<ForeignKey, Parent>

Foreign-key names and their parents for this column’s written value. Each cell retains the complete parent identity recorded by its setter.

Trait Implementations

impl<V: Clone> Clone for ColumnValue<V>

fn clone(&self) -> ColumnValue<V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<V: Debug> Debug for ColumnValue<V>

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

Formats the value using the given formatter.

impl<V: PartialEq> PartialEq for ColumnValue<V>

fn eq(&self, other: &ColumnValue<V>) -> 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.
