This follows a similar pattern to
Handle::spawn
to add the blocking spawn capabilities toHandle
. I took a fairly direct approach to changing the visibilities within the blocking modules to get this to work out, and I would understand if you'd rather have things locked down some more. Please let me know if there are any changes you'd like to see there.Motivation
We have an app with multiple runtimes, so we prefer to perform operations explicitly with handles rather than using the
tokio::task::*
spawn operators. However, handles don't currently offer an API to spawn a blocking computation.Solution
Adapts the implementation of
task::spawn_blocking
to use the blocking spawner that's already in the handle, guarded bycfg(blocking)
.
