Rewrite the type support, and use a plugin `Connector` architecture to support reconnection for PVI and Tango. Fixes #472, fixes #562, fixes #535, fixes #505, fixes #373, fixes #601 Required for #551 Structure now read from `.value` rather than `.pvi`. Supported in FastCS. Requires at least PandABlocks-ioc 0.10.0 ```python from enum import Enum class MyEnum(str, Enum): ONE = "one" TWO = "two" from ophyd_async.core import StrictEnum class MyEnum(StrictEnum): ONE = "one" TWO = "two" ``` ```python from ophyd_async.core import SubsetEnum MySubsetEnum = SubsetEnum["one", "two"] class MySubsetEnum(SubsetEnum): ONE = "one" TWO = "two" ``` ```python import numpy as np x = epics_signal_rw(np.int32, "PV") x = epics_signal_rw(int, "PV") ``` ```python import numpy as np import numpy.typing as npt x = epics_signal_rw(npt.NDArray[np.int32], "PV") from ophyd_async.core import Array1D x = epics_signal_rw(Array1D[np.int32], "PV") ``` ```python import numpy as np import numpy.typing as npt x = epics_signal_rw(npt.NDArray[np.str_], "PV") from collections.abc import Sequence x = epics_signal_rw(Sequence[str], "PV") ``` ```python fake_set_signal = SignalRW(MockSignalBackend(float)) fake_set_signal = soft_signal_rw(float) await fake_set_signal.connect(mock=True) ``` ```python get_mock_put(driver.capture).assert_called_once_with(Writing.ON, wait=ANY, timeout=ANY) get_mock_put(driver.capture).assert_called_once_with(Writing.ON, wait=ANY) ``` ```python class MyDevice(Device): def __init__(self, name: str = ""): self.signal, self.backend_put = soft_signal_r_and_setter(int) class MyDevice(Device): def __init__(self, name: str = ""): self.signal, self.backend_put = soft_signal_r_and_setter(int) super().__init__(name=name) ``` The `Table` type has been suitable for everything we have seen so far, if you need an arbitrary `BaseModel` subclass then please make an issue ```python class SourceDevice(Device): def __init__(self, name: str = ""): self.signal = soft_signal_rw(int) super().__init__(name=name) class ReferenceDevice(Device): def __init__(self, signal: SignalRW[int], name: str = ""): self.signal = signal super().__init__(name=name) def set(self, value) -> AsyncStatus: return self.signal.set(value + 1) from ophyd_async.core import Reference class ReferenceDevice(Device): def __init__(self, signal: SignalRW[int], name: str = ""): self._signal_ref = Reference(signal) super().__init__(name=name) def set(self, value) -> AsyncStatus: return self._signal_ref().set(value + 1) ```

When I try and do this I get an error of:
I can use a list to get round this but
numpyarrays are valid as normal PV signal types and so should be valid hereThe text was updated successfully, but these errors were encountered:
