Struct datafusion::logical_expr::SubqueryAlias

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

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<'static>

The alias for the input relation

schema: Arc<DFSchema>

The schema with qualified field names

Implementations

impl SubqueryAlias

pub fn try_new( plan: LogicalPlan, alias: impl Into<TableReference<'static>> ) -> Result<SubqueryAlias, DataFusionError>

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 Hash for SubqueryAlias

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

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
