Creates constraints for any structure that can create a database connection and execute SQL statements

Required methods

fn get_database_backend(&self) -> DatabaseBackend

Fetch the database backend as specified in DbBackend. This depends on feature flags enabled.

fn execute<'life0, 'async_trait>(
    &'life0 self,
    stmt: Statement
) -> Pin<Box<dyn Future<Output = Result<ExecResult, DbErr>> + Send + 'async_trait, Global>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Execute a Statement

fn query_one<'life0, 'async_trait>(
    &'life0 self,
    stmt: Statement
) -> Pin<Box<dyn Future<Output = Result<Option<QueryResult>, DbErr>> + Send + 'async_trait, Global>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Execute a Statement and return a query

fn query_all<'life0, 'async_trait>(
    &'life0 self,
    stmt: Statement
) -> Pin<Box<dyn Future<Output = Result<Vec<QueryResult, Global>, DbErr>> + Send + 'async_trait, Global>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Execute a Statement and return a collection Vec<QueryResult> on success

Provided methods

fn support_returning(&self) -> bool

Check if the connection supports RETURNING syntax on insert and update

fn is_mock_connection(&self) -> bool

Check if the connection is a test connection for the Mock database
