An LMDB error kind.

Variants

KeyExist

key/data pair already exists.

NotFound

key/data pair not found (EOF).

PageNotFound

Requested page not found - this usually indicates corruption.

Corrupted

Located page was wrong type.

Panic

Update of meta page failed or environment had fatal error.

VersionMismatch

Environment version mismatch.

Invalid

File is not a valid LMDB file.

MapFull

Environment mapsize reached.

DbsFull

Environment maxdbs reached.

ReadersFull

Environment maxreaders reached.

TlsFull

Too many TLS keys in use - Windows only.

TxnFull

Txn has too many dirty pages.

CursorFull

Cursor stack too deep - internal error.

PageFull

Page has not enough space - internal error.

MapResized

Database contents grew beyond environment mapsize.

Incompatible

MDB_Incompatible: Operation and DB incompatible, or DB flags changed.

BadRslot

Invalid reuse of reader locktable slot.

BadTxn

Transaction cannot recover - it must be aborted.

BadValSize

Unsupported size of key/DB name/data, or wrong DUP_FIXED size.

BadDbi

The specified DBI was changed unexpectedly.

Other(c_int)

Other error.

Implementations

impl Error

pub fn from_err_code(err_code: c_int) -> Error

Converts a raw error code to an Error.

pub fn to_err_code(&self) -> c_int

Converts an Error to the raw error code.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

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

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

The lower-level source of this error, if any.

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

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

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
