Struct FetchRel 

pub struct FetchRel {
    pub common: Option<RelCommon>,
    pub input: Option<Box<Rel>>,
    pub offset: i64,
    pub count: i64,
    pub advanced_extension: Option<AdvancedExtension>,
}

The relational operator representing LIMIT/OFFSET or TOP type semantics.

Fields

common: Option<RelCommon>

input: Option<Box<Rel>>

offset: i64

the offset expressed in number of records

count: i64

the amount of records to return use -1 to signal that ALL records should be returned

advanced_extension: Option<AdvancedExtension>

Trait Implementations

impl Clone for FetchRel

fn clone(&self) -> FetchRel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FetchRel

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

Formats the value using the given formatter.

impl Default for FetchRel

fn default() -> Self

Returns the “default value” for a type.

impl InputNode for FetchRel

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 FetchRel

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 FetchRel

fn eq(&self, other: &FetchRel) -> 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 ProtoMessage for FetchRel

fn proto_message_type() -> &'static str

Returns the protobuf type name for messages of this type.
