meshed.scrap.annotations_to_meshes.callable_annots_to_signature(callable_annots, mk_argname=<function try_annotation_name>)

Produces a signature from a Callable type annotation

Return type:

Signature

>>> from typing import Callable, NewType
>>> MyType = NewType('MyType', str)
>>> sig = callable_annots_to_signature(Callable[[MyType, str], str])
>>> import inspect
>>> isinstance(sig, inspect.Signature)
True
>>> list(sig.parameters.keys())
['self', 'mytype', 'arg_01']
>>> sig.parameters['arg_01'].annotation
<class 'str'>

Return type:

Protocol

meshed.scrap.annotations_to_meshes.func_types_to_scaffold(func_types, name=None)

Produces a scaffold class containing the said methods, with given annotations

Return type:

str
