cc @jhscheer would that be an appropriate fix for you ? |
|
Yes, this looks very good and solves my issue. Thanks! |

Note that non-boxing would require an enum that matches the CFG chaos of RecommendedWatcher, adding an enum for every possible configurable watcher combination. And otherwise we'll have to add the specific config calls to the trait. |

It'd be great if we could remove blank lines (i.e. follow rustfmt).

I guess we'll add/remove watchers in the future (actually, kqueue has been added recently) so it should make sense to add the #[non_exhaustive] attribute.
Note that non-boxing would require an enum that matches the CFG chaos of RecommendedWatcher, adding an enum for every possible configurable watcher combination. And otherwise we'll have to add the specific config calls to the trait. Closes #361
