```
client.Client.attached_window(self) -> Result<Option<crate::Window>, Error>
```

The current window of the session this client is attached to.

Not this client's own view. tmux keeps the current window on the
session -- `curw` is a member of `struct session`, not of
`struct client` -- so every client attached to one session reports the
same window, and one client changing it changes it for all of them.

`None` when the client is attached to nothing.

Costs one tmux command, as [`Self::attached_session`] describes.

# Errors

Returns an error when tmux cannot be reached, or answers with an ID
this crate cannot parse.
