)-> ‘Iterator[DascoreConfig]’
Temporarily override the runtime config for the current thread/task.
Parameters
| Parameter | Description |
|---|---|
| new_config |
A complete DascoreConfig to install.Mutually exclusive with keyword overrides. |
| **kwargs | Individual field overrides applied on top of the active config. |
Note
The override is stored in a ContextVar, so it is isolated per thread and task and restored when the block exits. Whether a newly started OS thread inherits a copy of the override is runtime-dependent (sys.flags.thread_inherit_context – normally enabled on free-threaded builds and disabled otherwise); an inherited copy is not undone by this block’s exit. For deterministic propagation, capture contextvars.copy_context() and run the worker with it, or rely on APIs that bind the config for you such as Spool.map.
