source · pub struct JoinError { /* private fields */ }
Expand description
Task failed to execute to completion.
Implementations§
source§impl JoinError
impl JoinError
sourcepub fn is_cancelled(&self) -> bool
pub fn is_cancelled(&self) -> bool
Returns true if the error was caused by the task being cancelled.
sourcepub fn is_panic(&self) -> bool
pub fn is_panic(&self) -> bool
Returns true if the error was caused by the task panicking.
Examples
use std::panic;
#[tokio::main]
async fn main() {
let err = tokio::spawn(async {
panic!("boom");
}).await.unwrap_err();
assert!(err.is_panic());
}
sourcepub fn into_panic(self) -> Box<dyn Any + Send, Global>
pub fn into_panic(self) -> Box<dyn Any + Send, Global>
Consumes the join error, returning the object with which the task panicked.
Panics
into_panic()
panics if the Error
does not represent the underlying
task terminating with a panic. Use is_panic
to check the error reason
or try_into_panic
for a variant that does not panic.
Examples
ⓘ
use std::panic;
#[tokio::main]
async fn main() {
let err = tokio::spawn(async {
panic!("boom");
}).await.unwrap_err();
if err.is_panic() {
// Resume the panic on the main task
panic::resume_unwind(err.into_panic());
}
}
sourcepub fn try_into_panic(self) -> Result<Box<dyn Any + Send, Global>, JoinError>
pub fn try_into_panic(self) -> Result<Box<dyn Any + Send, Global>, JoinError>
Consumes the join error, returning the object with which the task
panicked if the task terminated due to a panic. Otherwise, self
is
returned.
Examples
ⓘ
use std::panic;
#[tokio::main]
async fn main() {
let err = tokio::spawn(async {
panic!("boom");
}).await.unwrap_err();
if let Ok(reason) = err.try_into_panic() {
// Resume the panic on the main task
panic::resume_unwind(reason);
}
}
