Error type returned by database operations.

Variants

CompressionUnavailable

Support for compression is not available due to a disabled feature.

FileLockingUnavailable

Support for file locking is not available due to a disabled feature.

InvalidConfig

Provided configuration is invalid.

Fields

message: &'static str

Custom message.

BadChecksum

A calculated checksum does not match.

Fields

path: String

Path to file with bad checksum.

InvalidFileFormat

A file contained unexpected data or is not a database file.

Fields

path: String

Path to file.

message: &'static str

Custom message.

InvalidMetadata

The metadata file contains invalid data.

Fields

message: &'static str

Custom message.

InvalidPageData

A page file contains invalid data.

Fields

page: u64

Page ID.

message: &'static str

Custom message

LimitExceeded

An execution or resource limit was exceeded.

This error occurs if the tree is corrupted in such a way that it causes infinite loops.

Closed

Database is closed.

This occurs if the database experienced an error and will refuse to process future operations to prevent further corruption.

Locked

Database is locked.

Another process has locked the database for reading/writing.

ReadOnly

A modification to a database opened in read-only mode was requested.

Io(Error)

Other std IO error.

Other(Box<dyn Error + Send + Sync>)

Other internal errors.

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

Formats the value using the given formatter.

impl Error for Error

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.
