Enum ClientOperationError 

#[non_exhaustive]
pub enum ClientOperationError {
    RequestChannelClosed,
    RequestChannelFull,
}

Errors when handing an operation to the MQTT client’s request queue.

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.

RequestChannelClosed

The request channel to the event loop is closed (client shut down)

RequestChannelFull

The request channel to the event loop is full (backpressure)

Trait Implementations

impl Debug for ClientOperationError

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

Formats the value using the given formatter.

impl Display for ClientOperationError

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

impl Error for ClientOperationError

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<ClientOperationError> for MqttClientError

fn from(source: ClientOperationError) -> MqttClientError

Converts to this type from the input type.
