Struct MapPartitions 

pub struct MapPartitions {
    pub input: Option<Box<Relation>>,
    pub func: Option<CommonInlineUserDefinedFunction>,
    pub is_barrier: Option<bool>,
}

Fields

input: Option<Box<Relation>>

(Required) Input relation for a mapPartitions-equivalent API: mapInPandas, mapInArrow.

func: Option<CommonInlineUserDefinedFunction>

(Required) Input user-defined function.

is_barrier: Option<bool>

(Optional) Whether to use barrier mode execution or not.

Implementations

impl MapPartitions

pub fn is_barrier(&self) -> bool

Returns the value of is_barrier, or the default value if is_barrier is unset.

Trait Implementations

impl Clone for MapPartitions

fn clone(&self) -> MapPartitions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MapPartitions

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

Formats the value using the given formatter.

impl Default for MapPartitions

fn default() -> Self

Returns the “default value” for a type.

impl Message for MapPartitions

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for MapPartitions

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

Equality operator ==.

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

Inequality operator !=.
