Enum round_based::async_runtime::Error

#[non_exhaustive]
pub enum Error<E, RE, SE> {
    Recv(RE),

This is supported on crate feature async-runtime only.

Represents error that can occur while executing protocol

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.

Recv(RE)

Receiving next incoming message returned error

RecvEof

Incoming channel closed (got EOF)

Send(SE)

Sending outgoing message resulted in error

HandleIncoming(E)

Handling incoming message produced critical error

HandleIncomingTimeout(E)

Round timeout exceed when executor was waiting for new messages from other parties

ProceedPanicked(JoinError)

Proceed method panicked

Proceed(E)

State machine proceeding produced critical error

Finish(E)

StateMachine’s pick_output method return error

Exhausted

AsyncProtocol already executed protocol (or at least, tried to) and tired. You need to construct new executor!

BadStateMachine(BadStateMachineReason)

Buggy StateMachine implementation

InternalError(InternalError)

Buggy AsyncProtocol implementation!

If you’ve got this error, please, report bug.
