Trait Implementations

impl IAsyncConnection for PostgresConnection

fn execute<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, sql: &'life1 str, params: &'life2 [DbValue], ) -> Pin<Box<dyn Future<Output = EFResult<u64>> + Send + 'async_trait>>

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

Executes a query with parameters and returns the number of affected rows.

fn query<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, sql: &'life1 str, params: &'life2 [DbValue], ) -> Pin<Box<dyn Future<Output = EFResult<Vec<Vec<DbValue>>>> + Send + 'async_trait>>

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

Executes a query with parameters and returns rows.

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

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

Begins a transaction.

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

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

Commits the current transaction.

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

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

Rolls back the current transaction.

fn create_savepoint<'life0, 'life1, 'async_trait>( &'life0 mut self, name: &'life1 str, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'async_trait>>

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

Creates a savepoint within the current transaction.

fn release_savepoint<'life0, 'life1, 'async_trait>( &'life0 mut self, name: &'life1 str, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'async_trait>>

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

Releases (commits) a previously created savepoint, discarding its rollback point.

fn rollback_to_savepoint<'life0, 'life1, 'async_trait>( &'life0 mut self, name: &'life1 str, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'async_trait>>

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

Rolls back to the named savepoint, preserving the outer transaction.

fn set_transaction_isolation<'life0, 'async_trait>( &'life0 mut self, level: IsolationLevel, ) -> Pin<Box<dyn Future<Output = EFResult<()>> + Send + 'async_trait>>

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

Sets the isolation level of the current transaction. Must be called after begin_transaction and before any query.
