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

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§

source§

impl TransactionManagerStatus

source

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.

source

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
