Trait Implementations

impl Connection for PostgresqlConnection

fn begin_transaction(&mut self) -> Result<()>

Begins a new transaction.

fn close(&mut self) -> Result<()>

Releases this Connection object’s database and resources immediately instead of waiting for them to be automatically released.

fn commit_transaction(&mut self)

Commits the current transaction.

fn create_batch(&mut self) -> Result<Box<dyn Batch>>

Creates a new Batch instance for building a batched request.

fn create_savepoint(&mut self, name: &str)

Creates a savepoint in the current transaction. Arguments:

fn create_statement(&mut self, sql: &str) -> Result<Box<dyn Statement<'_> + '_>>

Creates a new statement for building a statement-based request. Arguments:

fn is_auto_commit(&mut self) -> bool

Returns the auto-commit mode for this connection.

fn metadata(&mut self) -> Result<Box<dyn ConnectionMetadata>>

Returns the ConnectionMetadata about the product this Connection is connected to.

fn transaction_isolation_level(&mut self) -> IsolationLevel

Returns the IsolationLevel for this connection.

fn release_savepoint(&mut self, name: &str)

Releases a savepoint in the current transaction. Calling this for drivers not supporting savepoint release results in a no-op. Arguments:

fn rollback_transaction(&mut self)

Rolls back the current transaction.

fn rollback_transaction_to_savepoint(&mut self, name: String)

Rolls back to a savepoint in the current transaction. Arguments:

fn auto_commit(&mut self, commit: bool)

Configures the auto-commit mode for the current transaction. If a connection is in auto-commit mode, then all Statements will be executed and committed as individual transactions. Otherwise, in explicit transaction mode, transactions have to be [beginTransaction()] started explicitly. A transaction needs to be either [commitTransaction()] committed or [rollbackTransaction()] rolled back to clean up the transaction state.

fn set_transaction_isolation_level(&mut self, isolation_level: IsolationLevel)

Configures the isolation level for the current transaction. Isolation level is typically one of the following constants:

fn validate(&mut self, depth: ValidationDepth) -> bool

Validates the connection according to the given ValidationDepth. Emits true if the validation was successful or false if the validation failed. Does not emit errors and does not complete empty. Arguments:
