Enum WriteMessageError 

pub enum WriteMessageError {
    ProcessNotFound(ProcessId),
    CannotSerializeMessage(String),
    ManagerCommunicationError(RecvError),
    IoError(Error),
    MessageWriterNotFound(ProcessId),
}

Error type returned when sending a message to the process.

Variants

ProcessNotFound(ProcessId)

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

CannotSerializeMessage(String)

Cannot serialize message to bytes. Includes error message.

ManagerCommunicationError(RecvError)

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

IoError(Error)

An unexpected IO error occurred when sending a message to the process.

MessageWriterNotFound(ProcessId)

The task used to send messages to 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

impl Debug for WriteMessageError

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

Formats the value using the given formatter.

impl Display for WriteMessageError

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

Formats the value using the given formatter.

impl Error for WriteMessageError

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.
