Struct.parse isn't exhaustively typed

[demberto]

def parse(data: bytes, **contextkw: ContextKWType) -> Container[Any]

This is the type hint you have used for it. However the docstring of this function mentions it can support a whole lot of other types (from bytes, bytearray, memoryview, array etc.). The closest type hint which comes to my mind is _typeshed.ReadableBuffer for this.

[demberto]

Also StreamType can be replaced with typing.BinaryIO instead, its the same (apart from an extra __enter__ method in the latter).

I used only bytes because until Python 3.10 the documentation says

typing.ByteString

This type represents the types bytes, bytearray, and memoryview of byte sequences.

As a shorthand for this type, bytes can be used to annotate arguments of any of the types mentioned above.

(see here)

But with PEP688 this will be removed. So I will change it in the future with a better type.

[demberto]

Since you mention PEP688 you can also use typing_extensions.Buffer. You will need to wait for a while tho, because even tho its present in typing_extensions, it isn't yet on typeshed. It will soon be
