Enum TaskError 

pub enum TaskError {
    Disconnected,
    Timeout,
    Panicked,
}

Errors that can occur when working with tasks in the runtime

These represent the various failure modes that can occur when scheduling, executing, or awaiting tasks.

Variants

Disconnected

The channel used to communicate with a task has been disconnected

This typically occurs when a task or its handle is dropped before the task completes.

Timeout

A timeout occurred while waiting for a task to complete

This can happen when using timeouts with task execution or when the runtime’s block_on method times out.

Panicked

The task panicked during execution

This error is produced when a task panics during its execution. The runtime attempts to capture and propagate this error safely.

Trait Implementations

impl Debug for TaskError

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

Formats the value using the given formatter.

impl Display for TaskError

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

Formats the value using the given formatter.

impl Error for TaskError

Available on crate feature std only.

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.
