Struct Passthrough 

pub struct Passthrough;

No-op InPlaceTransform. Useful for tests and library completeness.

Operators configuring surreal-sync via TOML should omit transforms entirely for identity; they do not need an explicit passthrough stage.

Pushing Passthrough into a pipeline does not make that pipeline’s identity check true — that requires an empty stage list. Config loading should collapse passthrough-only TOML to empty.

Trait Implementations

impl Clone for Passthrough

fn clone(&self) -> Passthrough

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Passthrough

impl Debug for Passthrough

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

Formats the value using the given formatter.

impl Default for Passthrough

fn default() -> Passthrough

Returns the “default value” for a type.

impl InPlaceTransform for Passthrough

fn transform( &self, _table: &str, _id: &mut Value, _fields: Option<&mut HashMap<String, Value>>, ) -> Result<()>

Mutate the shared document surface (id + optional field map).

fn transform_row(&self, row: &mut Row) -> Result<()>

Transform a single row in place.

fn transform_change(&self, change: &mut Change) -> Result<()>

Transform a single change in place (including deletes).

fn transform_relation(&self, _relation: &mut Relation) -> Result<()>

Transform a single relation in place. Default: no-op.

fn transform_relation_change(&self, _change: &mut RelationChange) -> Result<()>

Transform a single relation change in place. Default: no-op.

fn transform_rows_inplace(&self, rows: &mut [Row]) -> Result<()>

Transform a slice of owned rows in place (true zero-copy path).

fn transform_changes_inplace(&self, changes: &mut [Change]) -> Result<()>

Transform a slice of owned changes in place (true zero-copy path).

fn transform_relations_inplace(&self, relations: &mut [Relation]) -> Result<()>

Transform a slice of owned relations in place. Default: loop.

fn transform_relation_changes_inplace( &self, changes: &mut [RelationChange], ) -> Result<()>
