Possible database errors

Variants

BucketExists

Tried to create a bucket that already exists

BucketMissing

Tried to get a bucket that does not exist

KeyValueMissing

Tried to delete a key / value pair that does not exist

IncompatibleValue

Tried to get a bucket but found a key / value pair instead, or tried to put a key / value pair but found an existing bucket

ReadOnlyTx

Tried to write to a read only transaction

Io(Error)

Wrapper around a std::io::Error that occurred while opening the file or writing to it

Sync(&'static str)

Wrapper around a PoisonError

InvalidDB(String)

Error returned when the DB is found to be in an invalid state

Alloc(LayoutError)

Errors that can occur during allocation

Trait Implementations

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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

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 From<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.

impl From<LayoutError> for Error

fn from(err: LayoutError) -> Error

Converts to this type from the input type.

impl<T> From<PoisonError<T>> for Error

fn from(_: PoisonError<T>) -> Error

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Self) -> 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.
