Implementations

impl BatchFileScan

pub fn new(core: FileScanBackend) -> Self

pub fn column_names(&self) -> Vec<&str>

pub fn clone_with_dist(&self) -> Self

Methods from Deref<Target = PlanBase<Batch>>

pub fn clone_with_new_plan_id(&self) -> Self

pub fn clone_with_new_distribution(&self, dist: Distribution) -> Self

Panics if the plan node is not physical.

Trait Implementations

impl Clone for BatchFileScan

fn clone(&self) -> BatchFileScan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BatchFileScan

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

Formats the value using the given formatter.

impl Deref for BatchFileScan

type Target = PlanBase<Batch>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Distill for BatchFileScan

fn distill<'a>(&self) -> XmlNode<'a>

fn distill_to_string(&self) -> String

impl ExprRewritable<Batch> for BatchFileScan

fn has_rewritable_expr(&self) -> bool

fn rewrite_exprs(&self, _r: &mut dyn ExprRewriter) -> PlanRef<C>

impl ExprVisitable for BatchFileScan

fn visit_exprs(&self, _v: &mut dyn ExprVisitor)

impl Hash for BatchFileScan

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BatchFileScan

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

impl PlanNodeMeta for BatchFileScan

const NODE_TYPE: BatchPlanNodeType = BatchPlanNodeType::BatchFileScan

type Convention = Batch

fn plan_base(&self) -> &PlanBase<Batch>

Get the reference to the PlanBase with corresponding convention.

impl PlanTreeNode<Batch> for BatchFileScan

fn clone_with_inputs(&self, inputs: &[PlanRef<Batch>]) -> PlanRef<Batch>

Clone the node with a list of new inputs.

fn inputs(&self) -> SmallVec<[PlanRef<Batch>; 2]>

Get input nodes of the plan.

impl ToBatchPb for BatchFileScan

fn to_batch_prost_body(&self) -> NodeBody

impl ToDistributedBatch for BatchFileScan

fn to_distributed(&self) -> Result<PlanRef>

to_distributed is equivalent to to_distributed_with_required(&Order::any(), &RequiredDist::Any)

fn to_distributed_with_required( &self, required_order: &Order, required_dist: &RequiredDist, ) -> Result<BatchPlanRef>

insert the exchange in batch physical plan to satisfy the required Distribution and Order.

impl ToLocalBatch for BatchFileScan

fn to_local(&self) -> Result<PlanRef>

fn to_local_with_order_required( &self, required_order: &Order, ) -> Result<BatchPlanRef>

Convert the plan to batch local physical plan and satisfy the required Order
