Trait for async database connections.

Required Methods§

Source

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.

Source

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.

Source

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.

Source

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.

Source

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.

Source

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.

Source

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.

Source

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.

Source

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.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
