Fields

join_type: i32

condition: Option<ExprNode>

outer_side_key: Vec<u32>

inner_side_key: Vec<u32>

lookup_prefix_len: u32

inner_side_table_desc: Option<StorageTableDesc>

inner_side_vnode_mapping: Vec<u64>

inner_side_column_ids: Vec<i32>

output_indices: Vec<u32>

worker_nodes: Vec<WorkerNode>

null_safe: Vec<bool>

Null safe means it treats null = null as true. Each key pair can be null safe independently. (left_key, right_key, null_safe)

query_epoch: Option<BatchQueryEpoch>

asof_desc: Option<AsOfJoinDesc>

Trait Implementations

impl Clone for LocalLookupJoinNode

fn clone(&self) -> LocalLookupJoinNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LocalLookupJoinNode

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

Formats the value using the given formatter.

impl Default for LocalLookupJoinNode

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LocalLookupJoinNode

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for LocalLookupJoinNode

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,

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 LocalLookupJoinNode

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.
