Struct JoinError 

pub struct JoinError { /* private fields */ }

Why a task gave no output: it was cancelled (by its handle, an AbortHandle, or its runtime shutting down), or its future panicked.

Implementations

impl JoinError

pub fn is_cancelled(&self) -> bool

The task was cancelled.

pub fn is_panic(&self) -> bool

The task’s future panicked.

pub fn into_panic(self) -> Box<dyn Any + Send + 'static>

The payload of the panic.

Panics

When the task was cancelled, not panicked; try_into_panic answers it instead.

pub fn try_into_panic(self) -> Result<Box<dyn Any + Send + 'static>, JoinError>

The payload of the panic, or the error itself when the task was cancelled.

pub fn id(&self) -> Id

The id of the task.

Trait Implementations

impl Debug for JoinError

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

Formats the value using the given formatter.

impl Display for JoinError

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

Formats the value using the given formatter.

impl Error for JoinError

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<JoinError> for Error

fn from(error: JoinError) -> Self

Converts to this type from the input type.
