Struct JoinError 

pub struct JoinError(/* private fields */);

Available on crate feature futures only.

Task failure from awaiting a JoinHandle.

Implementations

impl JoinError

pub fn is_cancelled(&self) -> bool

Returns true if the handle was cancelled.

pub fn is_panic(&self) -> bool

Returns true if the task terminated with a panic.

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

Converts the error into a panic result.

Panics

Panics if the error is not a panic error. Use is_panic to check first if the error represents a panic.

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

Attempts to convert the error into a panic result.

Returns Err(self) if the error is not a panic result.

Trait Implementations

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.
