Represents all error cases for all routines of crate (including Tarantool errors)

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.

Tarantool(BoxError)

IO(Error)

Encode(EncodeError)

Decode

Fields

error: Error

expected_type: String

actual_msgpack: Vec<u8>

DecodeRmpValue(Error)

Unicode(Utf8Error)

NumValueRead(NumValueReadError)

ValueRead(ValueReadError)

ValueWrite(ValueWriteError)

Remote(BoxError)

Error returned from the Tarantool server.

It represents an error with which Tarantool server answers to the client in case of faulty request or an error during request execution on the server side.

Protocol(ProtocolError)

Tcp(Arc<Error>)

The error is wrapped in a Arc, because some libraries require error types to implement Sync, which isn’t implemented for Rc.

LuaError(LuaError)

MetaNotFound

MsgpackEncode(EncodeError)

MsgpackDecode(DecodeError)

ConnectionClosed(Arc<Error>)

A network connection was closed for the given reason.

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

This should only be used if the error doesn’t fall into one of the above categories.

Implementations

impl Error

pub fn other<E>(error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync>>,

pub fn decode<T>(error: Error, data: Vec<u8>) -> Self

pub const fn variant_name(&self) -> &'static str

Returns the name of the variant as it is spelled in the source code.

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
