Enum diesel::connection::TransactionManagerStatus

pub enum TransactionManagerStatus {
    Valid(ValidTransactionManagerStatus),
    InError,
}

Available on crate feature i-implement-a-third-party-backend-and-opt-into-breaking-changes only.

Status of the transaction manager

Variants

Valid(ValidTransactionManagerStatus)

Valid status, the manager can run operations

InError

Error status, probably following a broken connection. The manager will no longer run operations

Implementations

impl TransactionManagerStatus

pub fn transaction_depth(&self) -> QueryResult<Option<NonZeroU32>>

Returns the transaction depth if the transaction manager’s status is valid, or returns Error::BrokenTransactionManager if the transaction manager is in error.

pub fn is_not_broken_and_in_transaction(&self) -> bool

👎Deprecated: Removed without replacement

Whether we may be interested in calling set_top_level_transaction_requires_rollback_if_not_broken

You should typically not need this outside of a custom backend implementation

pub fn set_top_level_transaction_requires_rollback(&mut self)

👎Deprecated: Use set_requires_rollback_maybe_up_to_top_level instead

If in transaction and transaction manager is not broken, registers that the connection can not be used anymore until top-level transaction is rolled back

pub fn set_requires_rollback_maybe_up_to_top_level(&mut self, to: bool)

Available on crate features i-implement-a-third-party-backend-and-opt-into-breaking-changes or postgres or mysql only.

If in transaction and transaction manager is not broken, registers that it’s possible that the connection can not be used anymore until top-level transaction is rolled back.

If that is registered, savepoints rollbacks will still be attempted, but failure to do so will not result in an error. (Some may succeed, some may not.)

pub fn set_in_error(&mut self)

Sets the transaction manager status to InError

Subsequent attempts to use transaction-related features will result in a Error::BrokenTransactionManager error

Trait Implementations

impl Debug for TransactionManagerStatus

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

impl Default for TransactionManagerStatus

fn default() -> Self

Returns the “default value” for a type.
