A control event string could not be parsed into a known super::Ctl value.

InvalidUrl(String)

The supplied endpoint URL is malformed or unsupported.

RpcError(Error)

An error originating from the shared RPC error type.

ResponseHandler(String)

No pending response handler was registered for the given message id.

Disconnect

The WebSocket connection was disconnected.

NotificationMethod

A notification message did not include a method identifier.

WebSocketMessageType

The received WebSocket message type is incompatible with the active protocol.

MissingNotificationHandler

A notification was received but no notification handler is configured.

WebSocketError(WebSocketError)

Underlying WebSocket error

Timeout

RPC call timeout

ReceiverCtl

Unable to send shutdown message to receiver

NoDataInSuccessResponse

RPC call succeeded but no data was received in success response

NoDataInNotificationMessage

A notification message arrived without any payload data.

NoDataInErrorResponse

RPC call failed but no data was received in error response

ErrorDeserializingServerMessageData(Error)

Unable to deserialize response data

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.

impl Error for Error

fn custom<T: Display>(msg: T) -> Error

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.
