Struct substrait_validator::input::proto::substrait::expression::subquery::InPredicate

pub struct InPredicate {
    pub needles: Vec<Expression>,
    pub haystack: Option<Box<Rel>>,
}

Predicate checking that the left expression is contained in the right subquery

Examples:

x IN (SELECT * FROM t) (x, y) IN (SELECT a, b FROM t)

Fields

needles: Vec<Expression>

haystack: Option<Box<Rel>>

Trait Implementations

impl Clone for InPredicate

fn clone(&self) -> InPredicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InPredicate

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

Formats the value using the given formatter.

impl Default for InPredicate

fn default() -> Self

Returns the “default value” for a type.

impl InputNode for InPredicate

fn type_to_node() -> Node

Creates an empty output node for a protobuf datum of this type.

fn data_to_node(&self) -> Node

Creates an empty output node for a protobuf datum with this value.

fn oneof_variant(&self) -> Option<&'static str>

Returns the name of the selected variant of a oneof field, if this is a rust enum used to represent a oneof field.

fn parse_unknown(&self, y: &mut Context<'_>) -> bool

Complete the subtrees of this datum in output that have not already been parsed using UnknownField nodes. Returns whether any such nodes were added.

impl Message for InPredicate

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<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8, Global>

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8, Global>

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<InPredicate> for InPredicate

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl ProtoMessage for InPredicate

fn proto_message_type() -> &'static str

Returns the protobuf type name for messages of this type.
