Struct JoinRel 

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

The binary JOIN relational operator left-join-right, including various join types, a join condition, and an optional filter on the joined output.

Fields

common: Option<RelCommon>

left: Option<Box<Rel>>

right: Option<Box<Rel>>

expression: Option<Box<Expression>>

A boolean condition evaluated over the left and right inputs that determines whether a pair of records is a match.

post_join_filter: Option<Box<Expression>>

An optional boolean filter applied to each output record after join-type-specific output formation is complete. Semantically equivalent to placing a FilterRel directly above this join.

type: i32

advanced_extension: Option<AdvancedExtension>

Implementations

impl JoinRel

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 JoinRel

fn clone(&self) -> JoinRel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinRel

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

Formats the value using the given formatter.

impl Default for JoinRel

fn default() -> Self

Returns the “default value” for a type.

impl Message for JoinRel

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 Name for JoinRel

const NAME: &'static str = "JoinRel"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "substrait"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for JoinRel

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

Equality operator ==.

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

Inequality operator !=.
