Struct JoinBuilder

#[non_exhaustive]
pub struct JoinBuilder { /* private fields */ }

A builder for Join.

Implementations

impl JoinBuilder

pub fn name(self, input: impl Into<String>) -> Self

The name of the transform node.

This field is required.

pub fn set_name(self, input: Option<String>) -> Self

The name of the transform node.

pub fn get_name(&self) -> &Option<String>

The name of the transform node.

pub fn inputs(self, input: impl Into<String>) -> Self

Appends an item to inputs.

To override the contents of this collection use set_inputs.

The data inputs identified by their node names.

pub fn set_inputs(self, input: Option<Vec<String>>) -> Self

The data inputs identified by their node names.

pub fn get_inputs(&self) -> &Option<Vec<String>>

The data inputs identified by their node names.

pub fn join_type(self, input: JoinType) -> Self

Specifies the type of join to be performed on the datasets.

This field is required.

pub fn set_join_type(self, input: Option<JoinType>) -> Self

Specifies the type of join to be performed on the datasets.

pub fn get_join_type(&self) -> &Option<JoinType>

Specifies the type of join to be performed on the datasets.

pub fn columns(self, input: JoinColumn) -> Self

Appends an item to columns.

To override the contents of this collection use set_columns.

A list of the two columns to be joined.

pub fn set_columns(self, input: Option<Vec<JoinColumn>>) -> Self

A list of the two columns to be joined.

pub fn get_columns(&self) -> &Option<Vec<JoinColumn>>

A list of the two columns to be joined.

pub fn build(self) -> Result<Join, BuildError>

Consumes the builder and constructs a Join. This method will fail if any of the following fields are not set:

• name
• inputs
• join_type
• columns

Trait Implementations

impl Clone for JoinBuilder

fn clone(&self) -> JoinBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinBuilder

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

Formats the value using the given formatter.

impl Default for JoinBuilder

fn default() -> JoinBuilder

Returns the “default value” for a type.

impl PartialEq for JoinBuilder

fn eq(&self, other: &JoinBuilder) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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