pub fn
spawn
<F, T>(&'scope self, f: F) ->
ScopedJoinHandle
<'scope, T>
pub fn spawn <F, T>(&'scope self, f: F) -> ScopedJoinHandle <'scope, T>
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 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, use
Builder::spawn_scoped
instead.
§ Panics
Panics if the OS fails to create a thread; use
Builder::spawn_scoped
to recover from such errors.
