Expand description

An MDBX error kind.

Variants§

§

KeyExist

Key/data pair already exists.

§

NotFound

No matching key/data pair found.

§

NoData

The cursor is already at the end of data.

§

PageNotFound

Requested page not found.

§

Corrupted

Database is corrupted.

§

Panic

Fatal environment error.

§

VersionMismatch

DB version mismatch.

§

Invalid

File is not an MDBX file.

§

MapFull

Environment map size limit reached.

§

DbsFull

Too many DBI-handles (maxdbs reached).

§

ReadersFull

Too many readers (maxreaders reached).

§

TxnFull

Transaction has too many dirty pages (i.e., the transaction is too big).

§

CursorFull

Cursor stack limit reached.

§

PageFull

Page has no more space.

§

UnableExtendMapSize

The database engine was unable to extend mapping, e.g. the address space is unavailable or busy.

This can mean:

  • The database size was extended by other processes beyond the environment map size, and the engine was unable to extend the mapping while starting a read transaction. The environment should be re-opened to continue.
  • The engine was unable to extend the mapping during a write transaction or an explicit call to change the geometry of the environment.
§

Incompatible

Environment or database is not compatible with the requested operation or flags.

§

BadRslot

Invalid reuse of reader locktable slot.

§

BadTxn

Transaction is not valid for requested operation.

§

BadValSize

Invalid size or alignment of key or data for the target database.

§

BadDbi

The specified DBI-handle is invalid.

§

Problem

Unexpected internal error.

§

Busy

Another write transaction is running.

§

Multival

The specified key has more than one associated value.

§

BadSignature

Wrong signature of a runtime object(s).

§

WannaRecovery

Database should be recovered, but cannot be done automatically since it’s in read-only mode.

§

KeyMismatch

The given key value is mismatched to the current cursor position.

§

DecodeError

Decode error: An invalid parameter was specified.

§

Access

The environment opened in read-only.

§

TooLarge

Database is too large for the current system.

§

DecodeErrorLenDiff

Decode error length difference:

An invalid parameter was specified, or the environment has an active write transaction.

§

NestedTransactionsUnsupportedWithWriteMap

If the Environment was opened with EnvironmentKind::WriteMap flag, nested transactions are not supported.

§

WriteTransactionUnsupportedInReadOnlyMode

If the Environment was opened with in read-only mode Mode::ReadOnly, write transactions can’t be opened.

§

ReadTransactionTimeout

Read transaction has been timed out.

§

Permission

Permission defined

§

Other(i32)

Unknown error code.
