Struct NestedLoopJoinRel

pub struct NestedLoopJoinRel {
    pub common: Option<RelCommon>,
    pub left: Option<Box<Rel>>,
    pub right: Option<Box<Rel>>,
    pub expression: Option<Box<Expression>>,
    pub type: i32,
    pub advanced_extension: Option<AdvancedExtension>,
}

The nested loop join (NLJ) operator will hold the entire right input and iterate over it using the left input, evaluating the join expression on the Cartesian product of all rows.

Fields

common: Option<RelCommon>

left: Option<Box<Rel>>

right: Option<Box<Rel>>

expression: Option<Box<Expression>>

optional, defaults to true (a cartesian join)

type: i32

advanced_extension: Option<AdvancedExtension>

Implementations

impl NestedLoopJoinRel

pub fn type(&self) -> JoinType

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

pub fn set_type(&mut self, value: JoinType)

Sets type to the provided enum value.

Trait Implementations

impl Clone for NestedLoopJoinRel

fn clone(&self) -> NestedLoopJoinRel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NestedLoopJoinRel

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

Formats the value using the given formatter.

impl Default for NestedLoopJoinRel

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NestedLoopJoinRel

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for NestedLoopJoinRel

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 NestedLoopJoinRel

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.
