Implementations

impl<'c> YdbExecutor<'c>

pub fn retry(self) -> Self

configure executor to handle expired session error. In this case executor updates the session, then retries query

pub async fn send( &mut self, req: ExecuteDataQueryRequest, ) -> Result<YdbQueryResult, YdbError>

Trait Implementations

impl<'c> Debug for YdbExecutor<'c>

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

Formats the value using the given formatter.

impl<'c> Executor<'c> for YdbExecutor<'c>

type Database = Ydb

fn execute<'e, 'q: 'e, E>( self, query: E, ) -> BoxFuture<'e, Result<YdbQueryResult, Error>>

where E: Execute<'q, Self::Database> + 'q, 'c: 'e,

Execute the query and return the total number of rows affected.

fn fetch_many<'e, 'q: 'e, E>( self, query: E, ) -> BoxStream<'e, Result<Either<YdbQueryResult, YdbRow>, Error>>

where E: Execute<'q, Ydb> + 'q, 'c: 'e,

Execute multiple queries and return the generated results as a stream from each query, in a stream.

fn fetch_optional<'e, 'q: 'e, E>( self, query: E, ) -> BoxFuture<'e, Result<Option<YdbRow>, Error>>

where E: Execute<'q, Ydb> + 'q, 'c: 'e,

Execute the query and returns at most one row.

fn prepare<'e, 'q: 'e>( self, sql: &'q str, ) -> BoxFuture<'e, Result<YdbStatement, Error>>

where 'c: 'e,

Prepare the SQL query to inspect the type information of its parameters and results.

fn fetch_all<'e, 'q: 'e, E>( self, query: E, ) -> BoxFuture<'e, Result<Vec<YdbRow>, Error>>

where E: Execute<'q, Self::Database> + 'q, 'c: 'e,

fn fetch<'e, 'q: 'e, E>(self, query: E) -> BoxStream<'e, Result<YdbRow, Error>>

where E: Execute<'q, Self::Database> + 'q, 'c: 'e,

Execute the query and return the generated results as a stream.

fn fetch_one<'e, 'q: 'e, E>( self, query: E, ) -> BoxFuture<'e, Result<YdbRow, Error>>

where E: Execute<'q, Self::Database> + 'q, 'c: 'e,

Execute the query and returns exactly one row.

fn prepare_with<'e, 'q: 'e>( self, sql: &'q str, _parameters: &'e [YdbTypeInfo], ) -> BoxFuture<'e, Result<YdbStatement, Error>>

where 'c: 'e,

Prepare the SQL query, with parameter type information, to inspect the type information about its parameters and results.
