Trait Implementations

impl ConnectionTrait for SchemaManagerConnection<'_>

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>>

where 'life0: 'async_trait, SchemaManagerConnection<'_>: 'async_trait,

Execute a Statement

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, SchemaManagerConnection<'_>: 'async_trait,

Execute a unprepared Statement

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

where 'life0: 'async_trait, SchemaManagerConnection<'_>: '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>, DbErr>> + Send + 'async_trait>>

where 'life0: 'async_trait, SchemaManagerConnection<'_>: 'async_trait,

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

fn is_mock_connection(&self) -> bool

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

fn support_returning(&self) -> bool

Check if the connection supports RETURNING syntax on insert and update

impl<'c> IntoSchemaManagerConnection<'c> for SchemaManagerConnection<'c>

fn into_schema_manager_connection(self) -> SchemaManagerConnection<'c>

impl TransactionTrait for SchemaManagerConnection<'_>

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

where 'life0: 'async_trait, SchemaManagerConnection<'_>: 'async_trait,

Execute SQL BEGIN transaction. Returns a Transaction that can be committed or rolled back

fn begin_with_config<'life0, 'async_trait>( &'life0 self, isolation_level: Option<IsolationLevel>, access_mode: Option<AccessMode>, ) -> Pin<Box<dyn Future<Output = Result<DatabaseTransaction, DbErr>> + Send + 'async_trait>>

where 'life0: 'async_trait, SchemaManagerConnection<'_>: 'async_trait,

Execute SQL BEGIN transaction with isolation level and/or access mode. Returns a Transaction that can be committed or rolled back

fn transaction<'life0, 'async_trait, F, T, E>( &'life0 self, callback: F, ) -> Pin<Box<dyn Future<Output = Result<T, TransactionError<E>>> + Send + 'async_trait>>

where 'life0: 'async_trait, F: for<'a> FnOnce(&'a DatabaseTransaction) -> Pin<Box<dyn Future<Output = Result<T, E>> + Send + 'a>> + Send + 'async_trait, T: Send + 'async_trait, E: Error + Send + 'async_trait, SchemaManagerConnection<'_>: 'async_trait,

Execute the function inside a transaction. If the function returns an error, the transaction will be rolled back. If it does not return an error, the transaction will be committed.

fn transaction_with_config<'life0, 'async_trait, F, T, E>( &'life0 self, callback: F, isolation_level: Option<IsolationLevel>, access_mode: Option<AccessMode>, ) -> Pin<Box<dyn Future<Output = Result<T, TransactionError<E>>> + Send + 'async_trait>>

where 'life0: 'async_trait, F: for<'a> FnOnce(&'a DatabaseTransaction) -> Pin<Box<dyn Future<Output = Result<T, E>> + Send + 'a>> + Send + 'async_trait, T: Send + 'async_trait, E: Error + Send + 'async_trait, SchemaManagerConnection<'_>: 'async_trait,

Execute the function inside a transaction with isolation level and/or access mode. If the function returns an error, the transaction will be rolled back. If it does not return an error, the transaction will be committed.
