Feature gate: #![feature(thread_is_running)]

Public API

impl<T> JoinHandle<T> {
    /// Checks if the the associated thread is still running its main function.
    ///
    /// This might return `false` for a brief moment after the thread's main
    /// function has returned, but before the thread itself has stopped running.
    pub fn is_running(&self) -> bool;
}

Steps / History

  • Implementation: #90439
  • Final comment period (FCP)
  • Stabilization PR

Unresolved Questions

  • Do we also want to provide a way to access the result of the thread without having to .join() it? See #90439 (comment)
  • Do we also want this in the form of a Future? See #90439 (comment)
  • Name it is_finished instead?
