Struct SubqueryAlias

#[non_exhaustive]
pub struct SubqueryAlias {
    pub input: Arc<LogicalPlan>,
    pub alias: TableReference,
    pub schema: DFSchemaRef,
}

Aliased subquery

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

input: Arc<LogicalPlan>

The incoming logical plan

alias: TableReference

The alias for the input relation

schema: DFSchemaRef

The schema with qualified field names

Implementations

impl SubqueryAlias

pub fn try_new( plan: Arc<LogicalPlan>, alias: impl Into<TableReference>, ) -> Result<Self>

Trait Implementations

impl Clone for SubqueryAlias

fn clone(&self) -> SubqueryAlias

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SubqueryAlias

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

Formats the value using the given formatter.

impl Hash for SubqueryAlias

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 SubqueryAlias

fn eq(&self, other: &SubqueryAlias) -> 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 SubqueryAlias

fn partial_cmp(&self, other: &Self) -> 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.
