Struct ExecuteStreamChunk 

pub struct ExecuteStreamChunk {
    pub payload: Vec<u8>,
    pub watermark_lsn: u64,
}

One streamed chunk of an ExecuteStreamRequest result.

Mirrors a RowBatch on the coordinator side: payload is a standalone msgpack array of row elements (the exact bytes the Data Plane produced for a single scan frame); watermark_lsn is that frame’s read watermark. A streaming response is a sequence of these followed by exactly one ExecuteStreamEnd.

Fields

payload: Vec<u8>

watermark_lsn: u64

Trait Implementations

impl Archive for ExecuteStreamChunk

where Vec<u8>: Archive, u64: 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 = ArchivedExecuteStreamChunk

The archived representation of this type.

type Resolver = ExecuteStreamChunkResolver

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 ExecuteStreamChunk

fn clone(&self) -> ExecuteStreamChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecuteStreamChunk

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

Formats the value using the given formatter.

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

where Vec<u8>: Archive, <Vec<u8> as Archive>::Archived: Deserialize<Vec<u8>, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>,

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

Deserializes using the given deserializer

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

where Vec<u8>: Serialize<__S>, u64: 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.
