Expand description

An error originating from the TiKV client or dependencies.

Variants§

§

Unimplemented

Feature is not implemented.

§

DuplicateKeyInsertion

Duplicate key insertion happens.

§

ResolveLockError(Vec<LockInfo>)

Failed to resolve a lock

§

InvalidTransactionType

Will raise this error when using a pessimistic txn only operation on an optimistic txn

§

OperationAfterCommitError

It’s not allowed to perform operations in a transaction after it has been committed or rolled back.

§

OnePcFailure

We tried to use 1pc for a transaction, but it didn’t work. Probably should have used 2pc.

§

NoPrimaryKey

An operation requires a primary key, but the transaction was empty.

§

UnsupportedMode

For raw client, operation is not supported in atomic/non-atomic mode.

§

NoCurrentRegions

§

EntryNotFoundInRegionCache

§

Io(Error)

Wraps a std::io::Error.

§

Channel(RecvError)

Wraps a std::io::Error.

§

Grpc(Error)

Wraps a grpcio::Error.

§

GrpcAPI(Status)

Wraps a reqwest::Error. Wraps a grpcio::Error.

§

Url(InvalidUri)

Wraps a grpcio::Error.

§

Canceled(Canceled)

Represents that a futures oneshot channel was cancelled.

§

RegionError(Box<Error>)

Errors caused by changes of region information

§

UndeterminedError(Box<Error>)

Whether the transaction is committed or not is undetermined

§

KeyError(Box<KeyError>)

Wraps crate::proto::kvrpcpb::KeyError

§

ExtractedErrors(Vec<Error>)

Multiple errors generated from the ExtractError plan.

§

MultipleKeyErrors(Vec<Error>)

Multiple key errors

§

ColumnFamilyError(String)

Invalid ColumnFamily
