annotate mercurial/thirdparty/attr/setters.pyi @ 49643:e1c586b9a43c

attr: vendor 22.1.0

The previous version was 5 years old, and pytype 2022.06.30 started complaining
about various uses (e.g. seeing `mercurial.thirdparty.attr._make._CountingAttr`
instead of `bytearray`).  Hopefully this helps.  Additionally, this has official
python 3.11 support.

The `attrs` package is left out, because it is simply a bunch of *.pyi stubs and
`from attr.X import *`, and that's not how they've been used up to this point.
We'd probably need to customize those anyway to
`from mercurial.thirdparty.attr import *`.

from typing import Any, NewType, NoReturn, TypeVar, cast

from . import Attribute, _OnSetAttrType

_T = TypeVar("_T")

def frozen(
    instance: Any, attribute: Attribute[Any], new_value: Any
) -> NoReturn: ...
def pipe(*setters: _OnSetAttrType) -> _OnSetAttrType: ...
def validate(instance: Any, attribute: Attribute[_T], new_value: _T) -> _T: ...

# convert is allowed to return Any, because they can be chained using pipe.
def convert(
    instance: Any, attribute: Attribute[Any], new_value: Any
) -> Any: ...

_NoOpType = NewType("_NoOpType", object)
NO_OP: _NoOpType
