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 execute_many<'e, 'q: 'e, E>( self, query: E, ) -> BoxStream<'e, Result<YdbQueryResult, Error>>

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

Execute multiple queries and return the rows affected from each query, in a stream.

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

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

Execute the query and returns at most 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.

fn fetch<'e, 'q, E>( self, query: E, ) -> Pin<Box<dyn Stream<Item = Result<<Self::Database as Database>::Row, Error>> + Send + 'e>>

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

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

fn fetch_all<'e, 'q, E>( self, query: E, ) -> Pin<Box<dyn Future<Output = Result<Vec<<Self::Database as Database>::Row>, Error>> + Send + 'e>>

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

Execute the query and return all the generated results, collected into a Vec.

fn fetch_one<'e, 'q, E>( self, query: E, ) -> Pin<Box<dyn Future<Output = Result<<Self::Database as Database>::Row, Error>> + Send + 'e>>

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

Execute the query and returns exactly one row.

fn prepare<'e, 'q>( self, query: &'q str, ) -> Pin<Box<dyn Future<Output = Result<<Self::Database as HasStatement<'q>>::Statement, Error>> + Send + 'e>>

where 'q: 'e, 'c: 'e,

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