Enum ShutdownMode

pub enum ShutdownMode {
    Default,
    Transactional,
    TransactionalLocal,
    Immediate,
    Abort,
    Final,
}

Database shutdown mode

See Connection::shutdown_database.

Variants

Default

Further connects are prohibited. Waits for users to disconnect from the database.

Transactional

Further connects are prohibited and no new transactions are allowed. Waits for active transactions to complete.

TransactionalLocal

Further connects are prohibited and no new transactions are allowed. Waits only for local transactions to complete.

Immediate

Does not wait for current calls to complete or users to disconnect from the database. All uncommitted transactions are terminated and rolled back.

Abort

Does not wait for current calls to complete or users to disconnect from the database. All uncommitted transactions are terminated and are not rolled back. This is the fastest possible way to shut down the database, but the next database startup may require instance recovery. Therefore, this option should be used only in unusual circumstances; for example, if a background process terminates abnormally.

Final

Shuts down the database. Should be used only in the second call to Connection::shutdown_database after the database is closed and dismounted.

Trait Implementations

impl Clone for ShutdownMode

fn clone(&self) -> ShutdownMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ShutdownMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ShutdownMode

fn eq(&self, other: &ShutdownMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
