Expand description
The generic API for a database connection that can perform query or execute statements. It abstracts database connection and transaction
Required Methods§
sourcefn get_database_backend(&self) -> DatabaseBackend
fn get_database_backend(&self) -> DatabaseBackend
Fetch the database backend as specified in DbBackend. This depends on feature flags enabled.
sourcefn execute<'life0, 'async_trait>(
&'life0 self,
stmt: Statement
) -> Pin<Box<dyn Future<Output = Result<ExecResult, DbErr>> + Send + 'async_trait>>where
'life0: 'async_trait,
Self: 'async_trait,
fn execute<'life0, 'async_trait>(
&'life0 self,
stmt: Statement
) -> Pin<Box<dyn Future<Output = Result<ExecResult, DbErr>> + Send + 'async_trait>>where
'life0: 'async_trait,
Self: 'async_trait,
Execute a Statement
sourcefn execute_unprepared<'life0, 'life1, 'async_trait>(
&'life0 self,
sql: &'life1 str
) -> Pin<Box<dyn Future<Output = Result<ExecResult, DbErr>> + Send + 'async_trait>>where
'life0: 'async_trait,
'life1: 'async_trait,
Self: 'async_trait,
fn execute_unprepared<'life0, 'life1, 'async_trait>(
&'life0 self,
sql: &'life1 str
) -> Pin<Box<dyn Future<Output = Result<ExecResult, DbErr>> + Send + 'async_trait>>where
'life0: 'async_trait,
'life1: 'async_trait,
Self: 'async_trait,
Execute a unprepared Statement
Provided Methods§
sourcefn support_returning(&self) -> bool
fn support_returning(&self) -> bool
Check if the connection supports RETURNING
syntax on insert and update
sourcefn is_mock_connection(&self) -> bool
fn is_mock_connection(&self) -> bool
Check if the connection is a test connection for the Mock database
