Enum QueueError 

pub enum QueueError {
    QueueFull,
    QueueEmpty,
    ChannelDisconnected,
    Timeout,
    Unsupported(String),
    SendFailed(String),
    ReceiveFailed(String),
}

Errors that can occur during queue operations.

Variants

QueueFull

The queue is full and cannot accept more elements.

QueueEmpty

The queue is empty and has no elements to pop.

ChannelDisconnected

The channel has been disconnected (all senders/receivers dropped).

Timeout

A queue operation timed out.

Unsupported(String)

The requested operation is not supported by this queue type.

SendFailed(String)

Failed to send data through the queue.

ReceiveFailed(String)

Failed to receive data from the queue.

Trait Implementations

impl Debug for QueueError

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

Formats the value using the given formatter.

impl Display for QueueError

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

Formats the value using the given formatter.

impl Error for QueueError

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 PartialEq for QueueError

fn eq(&self, other: &QueueError) -> 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.
