CDRS custom error type. CDRS expects two types of error - errors returned by Server and internal errors occurred within the driver itself. Occasionally io::Error is a type that represent internal error because due to implementation IO errors only can be raised by CDRS driver. Server error is an error which are ones returned by a Server via result error frames.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

Internal IO error.

UuidParse(Error)

Internal error that may be raised during uuid::Uuid::from_bytes

General(String)

General error

FromUtf8(FromUtf8Error)

Internal error that may be raised during String::from_utf8

Utf8(Utf8Error)

Internal error that may be raised during str::from_utf8

Compression(CompressionError)

Internal Compression/Decompression error.

Server

Fields

body: ErrorBody

addr: SocketAddr

Server error.

Timeout(String)

Timed out waiting for an operation to complete.

UnknownConsistency(i16)

Unknown consistency.

UnknownServerEvent(String)

Unknown server event.

UnexpectedTopologyChangeType(String)

Unexpected topology change event type.

UnexpectedStatusChangeType(String)

Unexpected status change event type.

UnexpectedSchemaChangeType(String)

Unexpected schema change event type.

UnexpectedSchemaChangeTarget(String)

Unexpected schema change event target.

UnexpectedErrorCode(i32)

Unexpected additional error info.

UnexpectedWriteType(String)

Unexpected write type.

NonRequestOpcode(Opcode)

Expected a request opcode, got something else.

NonResponseOpcode(Opcode)

Expected a response opcode, got something else.

UnexpectedResultKind(i32)

Unexpected result kind.

UnexpectedColumnType(i16)

Unexpected column type.

InvalidReplicationFormat

Fields

keyspace: String

Invalid format found for given keyspace replication strategy.

UnexpectedAuthResponse(Opcode)

Unexpected response to auth message.

UnexpectedStartupResponse(Opcode)

Unexpected startup response.

InvalidProtocol(SocketAddr)

Special error for cases when starting up a connection and protocol negotiation fails. There currently is no explicit server-side code for this, so the information must be inferred from returned error response.

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<(), Error>

Formats the value using the given formatter.

impl Display for Error

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

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
