pub fn watch(
path: PathBuf,
changed: UnboundedSender<()>,
) -> Result<ConfigWatch, Error>Expand description
Watch path and send one () per burst of content changes to it.
§Errors
There is no Tokio runtime to own the watch task, or the initial watcher could not be created or armed. Whether that is fatal is the caller’s call: a running forge keeps serving and says it is not watching.
