# nw.transforms

### nw.transforms *= <Registry nw.transforms>*

A typed dict-backed plugin registry.

* **Parameters:**
  * **name** – Optional name; appears in error messages and `repr`.
  * **on_conflict** – `'error'` (default) raises `RegistryConflict` when registering
    a key that already exists. `'replace'` silently overwrites.
    `'keep'` silently keeps the original.
  * **(****dict****(****...****)** (*Implements MutableMapping so anything that takes a mapping*)

:param :
:param iteration:
:param length checks:
:param `in` lookups:
:param `.items()`) just works.:
