Struct Union

pub struct Union {
    pub inputs: Vec<Arc<LogicalPlan>>,
    pub schema: DFSchemaRef,
}

Union multiple inputs

Fields

inputs: Vec<Arc<LogicalPlan>>

Inputs to merge

schema: DFSchemaRef

Union schema. Should be the same for all inputs.

Implementations

impl Union

pub fn try_new_with_loose_types(inputs: Vec<Arc<LogicalPlan>>) -> Result<Self>

Constructs new Union instance deriving schema from inputs. Inputs do not have to have matching types and produced schema will take type from the first input.

Trait Implementations

impl Clone for Union

fn clone(&self) -> Union

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Union

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

Formats the value using the given formatter.

impl Hash for Union

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 Union

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

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.
