Implementations

impl DdlStatement

pub fn schema(&self) -> &DFSchemaRef

Get a reference to the logical plan’s schema

pub fn name(&self) -> &str

Return a descriptive string describing the type of this DdlStatement

pub fn inputs(&self) -> Vec<&LogicalPlan>

Return all inputs for this plan

pub fn display(&self) -> impl Display + '_

Return a formatable structure with the a human readable description of this LogicalPlan node per node, not including children.

See crate::LogicalPlan::display for an example

Trait Implementations

impl Clone for DdlStatement

fn clone(&self) -> DdlStatement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DdlStatement

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

Formats the value using the given formatter.

impl Hash for DdlStatement

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 DdlStatement

fn eq(&self, other: &DdlStatement) -> 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 PartialOrd for DdlStatement

fn partial_cmp(&self, other: &DdlStatement) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Eq for DdlStatement

impl StructuralPartialEq for DdlStatement
