Enum ReadMessageError 

pub enum ReadMessageError {
    ProcessNotFound(ProcessId),
    ManagerCommunicationError(RecvError),
    MessageReaderNotFound(ProcessId),
    MessageReaderKilled,
}

Error type returned when subscribing to a messages stream.

Variants

ProcessNotFound(ProcessId)

The process with given ID was not found (the ID is wrong or the process has been already killed).

ManagerCommunicationError(RecvError)

Cannot communicate with spawned process manager. Probably process manager task has been aborted.

MessageReaderNotFound(ProcessId)

Cannot get messages stream because a MessagingType has not been configured for the process.

MessageReaderKilled

The task used to read messages from a process has been killed. This error “shouldn’t” normally occur because the task is aborted when a process is being killed. And after this ProcessNotFound will be returned.

Trait Implementations

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
