Struct HavingClause 

pub struct HavingClause {
    pub aggregate: Option<HavingAggregate>,
    pub operator: i32,
    pub right: Option<Right>,
}

Single HAVING <aggregate> <op> <right> clause. Multiple entries in GetDocumentsRequestV1.having combine with implicit AND — same semantics as multiple where_clauses entries. HAVING COUNT(*) > 5 AND SUM(amount) > 100 is two HavingClause rows, not a tree.

The operator set mirrors WhereOperator minus STARTS_WITH (prefix matching has no natural meaning against a scalar aggregate result, even a string-typed one). BETWEEN* and IN operand semantics match WhereOperator: BETWEEN* expects a 2-element DocumentFieldValue.list carrying \[lower, upper\], and IN expects a list of candidate values (or a ranking set via right.ranking).

The right oneof carries either a concrete DocumentFieldValue (literal comparison target) or a HavingRanking (cross-group reference). Exactly one is set; the wire rejects an unset right.

Fields

aggregate: Option<HavingAggregate>

operator: i32

right: Option<Right>

Implementations

impl HavingClause

pub fn operator(&self) -> Operator

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

pub fn set_operator(&mut self, value: Operator)

Sets operator to the provided enum value.

Trait Implementations

impl Clone for HavingClause

fn clone(&self) -> HavingClause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HavingClause

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

Formats the value using the given formatter.

impl Default for HavingClause

fn default() -> HavingClause

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HavingClause

fn deserialize<__D>( __deserializer: __D, ) -> Result<HavingClause, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for HavingClause

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 Mockable for HavingClause

fn mock_serialize(&self) -> Option<Vec<u8>>

Serialize the message to bytes for mocking purposes.

fn mock_deserialize(data: &[u8]) -> Option<HavingClause>

Deserialize the message serialized with [mock_serialize()].

impl PartialEq for HavingClause

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

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
