Struct GrpcResultChunk 

pub struct GrpcResultChunk { /* private fields */ }

A single chunk of gRPC query results.

Each chunk contains Arrow IPC data (schema + record batch) and metadata about the chunk. The data is held as Bytes, so it shares the underlying allocation with the gRPC frame it was decoded from — cloning the chunk or extracting the bytes is a refcount bump, not a copy.

Implementations

impl GrpcResultChunk

pub fn chunk_id(&self) -> u64

Returns the chunk ID.

pub fn arrow_data(&self) -> &[u8]

Returns the Arrow IPC data for this chunk.

pub fn arrow_bytes(&self) -> Bytes

Returns the Arrow IPC data as a shared Bytes handle.

This is a refcount bump, not a copy — the returned Bytes shares the same allocation as the chunk.

pub fn into_arrow_data(self) -> Bytes

Consumes the chunk and returns the Arrow IPC data.

pub fn row_count(&self) -> Option<usize>

Returns the number of rows in this chunk, if known.

pub fn is_empty(&self) -> bool

Returns whether this chunk is empty (no data).
