Struct ResultSet 

#[non_exhaustive]
pub struct ResultSet {
    pub metadata: Option<ResultSetMetadata>,
    pub rows: Vec<ListValue>,
    pub stats: Option<ResultSetStats>,
    pub precommit_token: Option<MultiplexedSessionPrecommitToken>,
    pub cache_update: Option<CacheUpdate>,
    /* private fields */
}

Results from Read or ExecuteSql.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

metadata: Option<ResultSetMetadata>

Metadata about the result set, such as row type information.

rows: Vec<ListValue>

Each element in rows is a row whose format is defined by metadata.row_type. The ith element in each row matches the ith field in metadata.row_type. Elements are encoded based on type as described here.

stats: Option<ResultSetStats>

Query plan and execution statistics for the SQL statement that produced this result set. These can be requested by setting ExecuteSqlRequest.query_mode. DML statements always produce stats containing the number of rows modified, unless executed using the ExecuteSqlRequest.QueryMode.PLAN ExecuteSqlRequest.query_mode. Other fields might or might not be populated, based on the ExecuteSqlRequest.query_mode.

precommit_token: Option<MultiplexedSessionPrecommitToken>

Optional. A precommit token is included if the read-write transaction is on a multiplexed session. Pass the precommit token with the highest sequence number from this transaction attempt to the Commit request for this transaction.

cache_update: Option<CacheUpdate>

Optional. A cache update expresses a set of changes the client should incorporate into its location cache. The client should discard the changes if they are older than the data it already has. This data can be obtained in response to requests that included a RoutingHint field, but may also be obtained by explicit location-fetching RPCs which may be added in the future.

Implementations

impl ResultSet

pub fn new() -> Self

Creates a new default instance.

pub fn set_metadata<T>(self, v: T) -> Self

where T: Into<ResultSetMetadata>,

Sets the value of metadata.

pub fn set_or_clear_metadata<T>(self, v: Option<T>) -> Self

where T: Into<ResultSetMetadata>,

Sets or clears the value of metadata.

where T: Into<ResultSetStats>,

Sets the value of stats.

pub fn set_or_clear_stats<T>(self, v: Option<T>) -> Self

where T: Into<ResultSetStats>,

Sets or clears the value of stats.

pub fn set_or_clear_precommit_token<T>(self, v: Option<T>) -> Self

where T: Into<MultiplexedSessionPrecommitToken>,

Sets or clears the value of precommit_token.

pub fn set_cache_update<T>(self, v: T) -> Self

where T: Into<CacheUpdate>,

Trait Implementations

impl Clone for ResultSet

fn clone(&self) -> ResultSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResultSet

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

Formats the value using the given formatter.

impl Default for ResultSet

fn default() -> ResultSet

Returns the “default value” for a type.

impl Message for ResultSet

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ResultSet

fn eq(&self, other: &ResultSet) -> 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.
