Enum Response

pub enum Response {
    Metadata(ResultSetMetadata),
    Results(PartialResultSet),
}

The first response streamed from the server is of type ResultSetMetadata and includes information about the columns and types of the result set. From there on, we stream PartialResultSet messages with no additional information. PartialResultSet will contain resume_token to restart the response if query interrupts. In case of resumption with resume_token, the server will not resend the ResultSetMetadata.

Variants

Metadata(ResultSetMetadata)

Structure of rows in this response stream. The first (and only the first) response streamed from the server will be of this type.

Results(PartialResultSet)

A partial result set with row data potentially including additional instructions on how recent past and future partial responses should be interpreted.

Implementations

impl Response

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<Response>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for Response

fn clone(&self) -> Response

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Response

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

Formats the value using the given formatter.

impl PartialEq for Response

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

Tests for self and other values to be equal, and is used by ==.

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

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