Struct JoinRow 

pub struct JoinRow {
    pub timestamp: i64,
    pub key_value: Vec<u8>,
    pub data: Vec<u8>,
    pub matched: bool,
    /* private fields */
}

A stored join row containing serialized event data.

Fields

timestamp: i64

Event timestamp in milliseconds.

key_value: Vec<u8>

Serialized key value (as bytes).

data: Vec<u8>

Serialized record batch data.

matched: bool

Whether this row has been matched (for outer joins).

Implementations

impl JoinRow

pub fn to_batch(&self) -> Result<RecordBatch, OperatorError>

Converts this join row back to a record batch.

Errors

Returns OperatorError::SerializationFailed if the batch data is invalid.

pub fn encoding(&self) -> JoinRowEncoding

Returns the encoding used for this row.

Trait Implementations

impl Archive for JoinRow

where i64: Archive, Vec<u8>: Archive, bool: Archive, u8: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedJoinRow

The archived representation of this type.

type Resolver = JoinRowResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for JoinRow

fn clone(&self) -> JoinRow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinRow

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<JoinRow, __D> for Archived<JoinRow>

where i64: Archive, <i64 as Archive>::Archived: Deserialize<i64, __D>, Vec<u8>: Archive, <Vec<u8> as Archive>::Archived: Deserialize<Vec<u8>, __D>, bool: Archive, <bool as Archive>::Archived: Deserialize<bool, __D>, u8: Archive, <u8 as Archive>::Archived: Deserialize<u8, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<JoinRow, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<__S: Fallible + ?Sized> Serialize<__S> for JoinRow

where i64: Serialize<__S>, Vec<u8>: Serialize<__S>, bool: Serialize<__S>, u8: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
