```
window.Window.respawn(mut, command: Option<impl Into<OsString>>, respawn_mode: Respawn) -> Result<&mut Self, Error>
```

Restart the window's command in place.

Passing `None` reruns whatever the window started with. Every pane in
the window is replaced by the one the command runs in, which is what
makes this different from respawning a pane: [`crate::Pane::respawn`]
restarts one pane and leaves its neighbours alone.

# Errors

Returns an error when a pane is still running and `kill` is not set.
