Struct Loss 

pub struct Loss {
    pub row: RowId,
    pub generation: u64,
    pub frozen: bool,
    pub values: LossValues,
    pub cause: LossCause,
}

A loss independent of local SQLite identities. Active losses follow merge; frozen losses keep their values and cause after their merge history is gone.

Fields

row: RowId

Original table, key and audience.

generation: u64

Cell incarnation, removed-row generation, or excluded change’s generation.

frozen: bool

Whether this loss is frozen outside merge.

values: LossValues

Values as written, with each value’s setter.

cause: LossCause

What displaced these values.

Implementations

impl Loss

pub fn cell(row: RowId, key: LostKey, value: LostValue<Value>) -> Self

Project a concurrent merge loss into the common record.

pub fn freeze(self) -> Self

This loss frozen outside merge: it keeps its written values, setters, names and cause, without live parent links (D7).

pub fn removed(state: &RowState<Value>, rules: BTreeSet<Rule>) -> Self

Project a row removed by rules into the common record.

Trait Implementations

impl Clone for Loss

fn clone(&self) -> Loss

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Loss

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

Formats the value using the given formatter.

impl PartialEq for Loss

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