Enum ClientError 

pub enum ClientError<E> {
    Protocol(E),
    Timeout,
    Decode(Error),
    Transport(TransportError),
    Closed,
}

Everything that can go wrong sending or receiving a single OCPP action, flattened into one type instead of the Result<Result<Response, ProtocolError>, Box<dyn Error>> shape.

Variants

Protocol(E)

The other side answered with a CALLERROR.

Timeout

No CALLRESULT/CALLERROR arrived before the client’s timeout elapsed.

Decode(Error)

The payload didn’t match the expected request/response type.

Transport(TransportError)

The transport failed to send or receive a frame.

Closed

The connection was closed before a response arrived.

Trait Implementations

impl<E: Debug> Debug for ClientError<E>

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

Formats the value using the given formatter.

impl<E: ProtocolError> Display for ClientError<E>

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

Formats the value using the given formatter.

impl<E: ProtocolError> Error for ClientError<E>

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.
