Getting the full path to a modified file from an event

[hannobraun]

Before I answer, first a clarification: inotify-rs is just a wrapper around Linux's inotify API, and it doesn't really do a whole lot on top of that. Therefore what you describe is not a behavior of inotify-rs, but of inotify itself.

I can't speak to the intended usage, but I think it's unnecessary to create one Inotify instance per directory. You should be able to distinguish the events using the WatchDescriptor returned by the add_watch method. Event's field wd is a WatchDescriptor too, so you can use that to keep track of the various watches you added.

I'm going to close this issue, as I've answered the question. Feel free to post more comments though, if you have more questions, and feel free to reopen the issue if you believe there's something in inotify-rs that needs to be changed.

I'd like to add that there are known bugs in the version on crates.io (0.4.1), that have been fixed but not published. One of the bugs (see #60) is specific to WatchDescriptor and can potentially break your application. I suggest linking the dependency to the repository in your cargo.toml like so:

inotify = { git = "https://github.com/hannobraun/inotify-rs.git", branch = "master" }

The master branch has breaking changes, and some of the documentation needs to be updated to reflect that. Be aware that there are still bugs that need fixing.

Reading the Inotify man pages will be of great help. Inotify has it's quirks and it only helps to be aware of them when implementing the library.

Thank you for the answers, I ended up going with the notify wrapper over this since it seems to implement all the functionality I need in a (hopefully reasonably fast) way.

I will however use the github rolling release style dependency with that one, since it probably uses 0.4.1 itself.

I think notify is the right choice for most uses cases. It's a bit behind with its depdency on inotify-rs though, it still depends on 0.3.0.
