Enum ProtoError

#[non_exhaustive]
pub enum ProtoError {
    Shutdown(ShutdownError),
    InvalidRequest(InvalidRequestError),
    RequestIdInUse,
    RequestCompleted,
    DuplicateWait,
    CouldNotEncode(Arc<Error>),
    InternalRequestFailed(UnexpectedReply),
}

An error that has occurred while launching an RPC command.

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.

Shutdown(ShutdownError)

The RPC connection failed, or was closed by the other side.

InvalidRequest(InvalidRequestError)

There was a problem in the request we tried to send.

RequestIdInUse

We tried to send a request with an ID that was already pending.

RequestCompleted

We tried to wait for or inspect a request that had already succeeded or failed.

DuplicateWait

We tried to wait for the same request more than once.

(This should be impossible.)

CouldNotEncode(Arc<Error>)

We got an internal error while trying to encode an RPC request.

(This should be impossible.)

InternalRequestFailed(UnexpectedReply)

We got a response to some internally generated request that wasn’t what we expected.

Trait Implementations

impl Clone for ProtoError

fn clone(&self) -> ProtoError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProtoError

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

Formats the value using the given formatter.

impl Display for ProtoError

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