```
window.Window.rename(mut, name: impl Into<TmuxArg>) -> Result<&mut Self, Error>
```

Rename the window and update this handle.

The name belongs to the window, so every session linking it sees the
change.

# Errors

Returns an error when tmux refuses the name.
tmux expands the name as a format before it checks it, so `#(command)`
in one runs a shell command. See [the crate documentation][crate#a-name-reaches-tmux-as-a-format]
before passing text a caller supplied.
