Which Watcher do I get?

[jhscheer]

I would like to know which Watcher RecommendedWatcher::new() returns.

For example if let mut watcher = RecommendedWatcher::new(tx)?; returns a PollWatcher I would like to set the delay manually (the default is 30 seconds and cannot be adjusted later).

Maybe something like,

1. either add an Option<Duration> parameter to Watcher::new() which will be relevant only if type RecommendedWatcher = PollWatcher; Then I could call let mut watcher = RecommendedWatcher::new(tx, Some(Duration::from_secs(1)))?;
2. or add a whoami() method to the Watcher trait and implement setting the delay with configure(). Then I could call, e.g.

let mut watcher = RecommendedWatcher::new(tx)?;
if watcher.whoami == WatcherType::PollWatcher {
    watcher.configure(Config::SetDelay(Duration::from_secs(1)))?;
}

The idea isn't bad, we'll need to add an enum for each type that is part of the trait, you can do a PR if you want.
FYI: You should only get the pollwatcher on anything that's not *BSD,nix,Windows,MacOS.

I may have an implementation that sidesteps adding the params for PollWatcher to the trait.
