Invalid input to the pure merge; no partially changed state is returned.

Variants

MillisecondsOutOfRange(u64)

Milliseconds do not fit in the timestamp’s 48 bits.

TimestampExhausted

The final millisecond and counter have both been used.

GenerationExhausted

Advancing a generation would exceed its representation.

GenerationParity(u64)

An insert was not made at an even generation, or an edit/delete at an odd one.

GenerationNotSeen

No write the author had read moved this row to the specified generation.

Fields

row: RowId

The row, including its audience.

generation: u64

The generation the change was made at.

GenerationAhead

Causality has not brought the receiving row to this generation.

Fields

row: RowId

The receiving row.

MissingWrite(WriteId)

A required write is missing from the applied set.

DuplicateWrite(WriteId)

A write occurs twice in the input or has already been applied.

DuplicateTimestamp(WriteId, WriteId)

Two different writes have equal timestamps.

CausalTimestamp(WriteId)

A timestamp is not larger than that of a write its author had read.

CausalClosure(WriteId)

A write’s recorded past omits a predecessor of a write it had read: its read_through is below that of its device’s last landed write.

TimestampDevice(WriteId)

The timestamp’s device is different from the write’s device.

MissingChange(RowId)

A write’s row changes do not include the row passed to apply.

ParentGeneration(u64)

A parent generation must name an existing incarnation, an odd generation.

ReferenceAudience(RowId)

A reference reaches an audience some readers of the child cannot read.

DuplicateRow(RowId)

The removal view listed a row more than once.

GenerationGap(u64)

Stored generations must be contiguous from one through the current one.

GenerationTimestamp(u64)

Each generation must be stamped after the preceding generation.

DeletedRowHasCells

A deleted row cannot retain winning cells.

CellBeforeIncarnation(String)

A cell’s setter cannot precede the start of its incarnation.

InvalidLostValue(LostKey)

A lost record has an invalid incarnation or canonical replacer.

Trait Implementations

impl Clone for MergeError

fn clone(&self) -> MergeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MergeError

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

Formats the value using the given formatter.

impl Display for MergeError

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

Formats the value using the given formatter.

impl Error for MergeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for MergeError

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