impl DbExecutor for PostgresExecutor

fn execute<'life0, 'life1, 'async_trait>( &'life0 self, req: ExecRequest<'life1>, ) -> Pin<Box<dyn Future<Output = Result<ExecOutcome, ExecError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn execute_streaming<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, req: ExecRequest<'life1>, sink: &'life2 mut (dyn RowSink + Send), ) -> Pin<Box<dyn Future<Output = Result<StreamOutcome, ExecError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

fn tx_begin<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, session_name: &'life1 str, session_cfg: &'life2 SessionConfig, read_only: bool, ) -> Pin<Box<dyn Future<Output = Result<(), ExecError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Open an explicit transaction on the named session. Subsequent execute/execute_streaming calls on that session bypass the implicit per-query BEGIN..COMMIT wrap until tx_commit or tx_rollback is called.

fn tx_commit<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, session_name: &'life1 str, session_cfg: &'life2 SessionConfig, ) -> Pin<Box<dyn Future<Output = Result<(), ExecError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

fn tx_rollback<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, session_name: &'life1 str, session_cfg: &'life2 SessionConfig, ) -> Pin<Box<dyn Future<Output = Result<(), ExecError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

fn prepare_only<'life0, 'life1, 'async_trait>( &'life0 self, req: ExecRequest<'life1>, ) -> Pin<Box<dyn Future<Output = Result<DryRunOutcome, ExecError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Validate sql and the param shape without running the statement. The server prepares the statement inside a transaction that is rolled back, returning the inferred parameter types and column metadata.

fn invalidate_sessions<'life0, 'life1, 'async_trait>( &'life0 self, session_names: &'life1 [String], ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn shutdown<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

impl Default for PostgresExecutor

fn default() -> Self

Returns the “default value” for a type.
