Struct google_api_proto::google::bigtable::v2::ReadRowsResponse

pub struct ReadRowsResponse {
    pub chunks: Vec<CellChunk>,
    pub last_scanned_row_key: Bytes,
    pub request_stats: Option<RequestStats>,
}

Response message for Bigtable.ReadRows.

Fields

chunks: Vec<CellChunk>

A collection of a row’s contents as part of the read request.

last_scanned_row_key: Bytes

Optionally the server might return the row key of the last row it has scanned. The client can use this to construct a more efficient retry request if needed: any row keys or portions of ranges less than this row key can be dropped from the request. This is primarily useful for cases where the server has read a lot of data that was filtered out since the last committed row key, allowing the client to skip that work on a retry.

request_stats: Option<RequestStats>

If requested, provide enhanced query performance statistics. The semantics dictate:

• request_stats is empty on every (streamed) response, except
• request_stats has non-empty information after all chunks have been streamed, where the ReadRowsResponse message only contains request_stats.
  • For example, if a read request would have returned an empty response instead a single ReadRowsResponse is streamed with empty chunks and request_stats filled.

Visually, response messages will stream as follows: … -> {chunks: […]} -> {chunks: [], request_stats: {…}} _/ ___________/ Primary response Trailer of RequestStats info

Or if the read did not return any values: {chunks: [], request_stats: {…}} ________________________________/ Trailer of RequestStats info

Trait Implementations

impl Clone for ReadRowsResponse

fn clone(&self) -> ReadRowsResponse

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReadRowsResponse

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

Formats the value using the given formatter.

impl Default for ReadRowsResponse

fn default() -> Self

Returns the “default value” for a type.

impl Message for ReadRowsResponse

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 PartialEq for ReadRowsResponse

fn eq(&self, other: &ReadRowsResponse) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
