Enum ServerError 

pub enum ServerError {
    Close,
    Timeout,
    NoData,
    NotFound,
    PoisonError,
    NonBorshRequest,
    NonSerdeRequest,

    Data(Vec<u8>),
    Text(String),
    WebSocketError(String),
    ReceiveChannelRx,
    ReceiveChannelTx,
}

ServerError enum is used by both Server and Client and represents errors returned by server-side handlers. This enum is also serialized and transported to the client when using the Borsh protocol (as such, this mostly contains pure enum values).

Variants

Close

The connection has been closed.

Timeout

The RPC call did not complete within the allotted time.

NoData

No data was available where data was expected.

NotFound

No handler was registered for the requested RPC method.

PoisonError

A lock was poisoned by a panic in another thread.

NonBorshRequest

The request was expected to use the Borsh protocol but did not.

NonSerdeRequest

The request was expected to use the serde/JSON protocol but did not.

ReqSerialize

The request could not be serialized.

ReqDeserialize

The request could not be deserialized.

RespSerialize

The response could not be serialized.

NotificationDeserialize(String)

A notification payload could not be deserialized.

RespDeserialize(String)

A response payload could not be deserialized.

Data(Vec<u8>)

Opaque binary error payload.

Text(String)

Free-form textual error message.

WebSocketError(String)

Underlying WebSocket error

ReceiveChannelRx

Failure receiving from an internal receiver channel.

ReceiveChannelTx

Failure sending to an internal receiver channel.

Trait Implementations

impl BorshDeserialize for ServerError

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for ServerError

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for ServerError

fn clone(&self) -> ServerError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ServerError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ServerError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ServerError

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

Formats the value using the given formatter.

impl EnumExt for ServerError

fn deserialize_variant<__R: Read>( reader: &mut __R, variant_tag: u8, ) -> Result<Self, Error>

Deserialises given variant of an enum from the reader.

impl Eq for ServerError

impl Error for ServerError

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 From<&str> for ServerError

fn from(error: &str) -> Self

Converts to this type from the input type.

impl From<Error> for ServerError

fn from(_err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ServerError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl<T> From<PoisonError<T>> for ServerError

fn from(_error: PoisonError<T>) -> ServerError

Converts to this type from the input type.

impl From<RecvError> for ServerError

fn from(_: RecvError) -> ServerError

Converts to this type from the input type.

impl<T> From<SendError<T>> for ServerError

fn from(_error: SendError<T>) -> ServerError

Converts to this type from the input type.

impl From<ServerError> for Error

fn from(err: ServerError) -> Self

Converts to this type from the input type.

impl From<ServerError> for JsonServerError

fn from(err: ServerError) -> Self

Converts to this type from the input type.

impl From<String> for ServerError

fn from(error: String) -> Self

Converts to this type from the input type.

impl<T> From<TrySendError<T>> for ServerError

fn from(_error: TrySendError<T>) -> ServerError

Converts to this type from the input type.

impl PartialEq for ServerError

fn eq(&self, other: &ServerError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ServerError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
