Struct ArrangeNode

pub struct ArrangeNode {
    pub table_info: Option<ArrangementInfo>,
    pub distribution_key: Vec<u32>,
    pub table: Option<Table>,
}

Special node for shared state, which will only be produced in fragmenter. ArrangeNode will produce a special Materialize executor, which materializes data for downstream to query.

Fields

table_info: Option<ArrangementInfo>

Info about the arrangement

distribution_key: Vec<u32>

Hash key of the materialize node, which is a subset of pk.

table: Option<Table>

Used for internal table states.

Implementations

impl ArrangeNode

pub fn get_table_info(&self) -> Result<&ArrangementInfo, PbFieldNotFound>

pub fn get_distribution_key(&self) -> &Vec<u32>

pub fn get_table(&self) -> Result<&Table, PbFieldNotFound>

Trait Implementations

impl Clone for ArrangeNode

fn clone(&self) -> ArrangeNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArrangeNode

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

Formats the value using the given formatter.

impl Default for ArrangeNode

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ArrangeNode

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for ArrangeNode

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 ArrangeNode

fn eq(&self, other: &ArrangeNode) -> 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 Serialize for ArrangeNode

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
