Enum TransactionError 

pub enum TransactionError<P: PendingManager> {
    ReadOnly,
    Conflict,
    Discard,
    LargeTxn,
    Manager(P::Error),
}

Error type for the transaction.

Variants

ReadOnly

Returned if an update function is called on a read-only transaction.

Conflict

Returned when a transaction conflicts with another transaction. This can happen if the read rows had been updated concurrently by another transaction.

Discard

Returned if a previously discarded transaction is re-used.

LargeTxn

Returned if too many writes are fit into a single transaction.

Manager(P::Error)

Returned if the transaction manager error occurs.

Trait Implementations

impl<P: PendingManager> Debug for TransactionError<P>

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

Formats the value using the given formatter.

impl<P: PendingManager> Display for TransactionError<P>

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

Formats the value using the given formatter.

impl<P: PendingManager> Error for TransactionError<P>

where Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<D: Database, P: PendingManager> From<TransactionError<P>> for Error<D, P>

fn from(source: TransactionError<P>) -> Self

Converts to this type from the input type.
