Enum AsyncError 

pub enum AsyncError {
    Mbus(MbusError),
    WorkerClosed,
    UnexpectedResponseType,
    Timeout,
}

Async facade error type.

Variants

Mbus(MbusError)

Error propagated from the underlying Modbus client stack.

WorkerClosed

Background worker channel is closed or worker thread has stopped.

UnexpectedResponseType

Internal response routing mismatch between request and callback payload type.

Timeout

Per-request timeout elapsed before the server responded.

Set via AsyncClientCore::set_request_timeout. The in-flight entry remains in the background task until the transport delivers or errors; call connect to reset transport state.

Trait Implementations

impl Debug for AsyncError

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

Formats the value using the given formatter.

impl Display for AsyncError

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

Formats the value using the given formatter.

impl Eq for AsyncError

impl Error for AsyncError

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.

impl From<MbusError> for AsyncError

fn from(value: MbusError) -> AsyncError

Converts to this type from the input type.

impl PartialEq for AsyncError

fn eq(&self, other: &AsyncError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
