Fields

group_expr: Vec<PhysicalExprNode>

aggr_expr: Vec<PhysicalExprNode>

mode: i32

input: Option<Box<PhysicalPlanNode>>

group_expr_name: Vec<String>

aggr_expr_name: Vec<String>

input_schema: Option<Schema>

we need the input schema to the partial aggregate to pass to the final aggregate

null_expr: Vec<PhysicalExprNode>

groups: Vec<bool>

filter_expr: Vec<MaybeFilter>

limit: Option<AggLimit>

Implementations

impl AggregateExecNode

pub fn mode(&self) -> AggregateMode

Returns the enum value of mode, or the default if the field is set to an invalid enum value.

pub fn set_mode(&mut self, value: AggregateMode)

Sets mode to the provided enum value.

Trait Implementations

impl Clone for AggregateExecNode

fn clone(&self) -> AggregateExecNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AggregateExecNode

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

Formats the value using the given formatter.

impl Default for AggregateExecNode

fn default() -> Self

Returns the “default value” for a type.

impl Message for AggregateExecNode

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 AggregateExecNode

fn eq(&self, other: &AggregateExecNode) -> 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.
