Struct TableRow 

pub struct TableRow {
    pub version_timestamp: i64,
    pub key_value: Vec<u8>,
    pub data: Vec<u8>,
}

A stored table row for temporal joining.

Fields

version_timestamp: i64

Version timestamp (when this row became valid).

key_value: Vec<u8>

Serialized key value.

data: Vec<u8>

Serialized record batch data.

Implementations

impl TableRow

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

Converts this row back to a record batch.

Errors

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

Trait Implementations

impl Archive for TableRow

where i64: Archive, Vec<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 = ArchivedTableRow

The archived representation of this type.

type Resolver = TableRowResolver

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 TableRow

fn clone(&self) -> TableRow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableRow

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

Formats the value using the given formatter.

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

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

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

Deserializes using the given deserializer

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

where i64: Serialize<__S>, Vec<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.
