1.63.0 · Source
Spawns a new thread within a scope, returning a ScopedJoinHandle for it.
Unlike non-scoped threads, threads spawned with this function may borrow non-'static data from the outside the scope. See scope for details.
The join handle provides a join method that can be used to join the spawned thread. If the spawned thread panics, join will return an Err containing the panic payload.
If the join handle is dropped, the spawned thread will be implicitly joined at the end of the scope. In that case, if the spawned thread panics, scope will panic after all threads are joined.
This call will create a thread using default parameters of Builder. If you want to specify the stack size or the name of the thread, useBuilder::spawn_scoped instead.
§Panics
Panics if the OS fails to create a thread; use Builder::spawn_scopedto recover from such errors.
