Struct FetchRel

pub struct FetchRel {
    pub common: Option<RelCommon>,
    pub input: Option<Box<Rel>>,
    pub advanced_extension: Option<AdvancedExtension>,
    pub offset_mode: Option<OffsetMode>,
    pub count_mode: Option<CountMode>,
}

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

Fields

common: Option<RelCommon>

input: Option<Box<Rel>>

advanced_extension: Option<AdvancedExtension>

offset_mode: Option<OffsetMode>

Note: A oneof field is inherently optional, whereas individual fields within a oneof cannot be marked as optional. The unset state of offset should therefore be checked at the oneof level. Unset is treated as 0.

count_mode: Option<CountMode>

Note: A oneof field is inherently optional, whereas individual fields within a oneof cannot be marked as optional. The unset state of count should therefore be checked at the oneof level. Unset is treated as ALL.

Trait Implementations

impl Clone for FetchRel

fn clone(&self) -> FetchRel

Returns a copy 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<'de> Deserialize<'de> for FetchRel

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Serialize for FetchRel

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

where S: Serializer,

Serialize this value into the given Serde serializer.
