Struct RunToken

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

Similar to a [tokio_util::sync::CancellationToken], the RunToken encapsulates the possibility of canceling an async command. However it also allows pausing and resuming the async command, and it is possible to wait in both a blocking fashion and an asynchronous fashion.

Implementations

impl RunToken

pub fn new() -> Self

Construct a new running run token

pub fn cancel(&self)

Cancel computation

pub fn is_cancelled(&self) -> bool

Return true iff we are canceled

pub fn cancelled(&self) -> WaitForCancellationFuture<'_>

Suspend the async coroutine until cancel() is called

pub fn set_location_file_line(&self, file_line_str: &'static str)

Store a file line location in the run_token The string must be on the form “file:line\0”

You probably want to call the [set_location] macro instead

pub fn location(&self) -> Option<(&'static str, u32)>

Retrieve the stored file,live location in the run_token
