Actor process spawning machinery using multiple backends.
|
|
|
|
- `._spawn`: cross-backend subactor-as-sub[proc|int] spawning
|
|
and supervision routines.
|
|
|
|
Per-backend submodules (each exposes a single `*_proc()`
|
|
coroutine registered in `_spawn._methods`):
|
|
|
|
- `._trio`: the `trio`-native subprocess backend (default,
|
|
all platforms), spawns via `trio.lowlevel.open_process()`.
|
|
|
|
- `._mp`: the stdlib `multiprocessing` backend variants — driven by
|
|
the `mp.context` bound to `_spawn._ctx`:
|
|
* `'mp_spawn'`,
|
|
* `'mp_forkserver'`
|
|
|
|
Entry-point helpers live in `._entry`/`._mp_fixup_main`/
|
|
`._forkserver_override`.
|
|
|
|
NOTE: to avoid circular imports, this ``__init__`` does NOT eagerly
|
|
import submodules.
