Custom storage implementation

[mitar]

Any plans to support custom storage implementations, so that I could store files into cloud storage for example? Or even memory? It seems that for memory I could use a tmpfs mount point and then direct the library to store everything there, but having things in Go process might be easier to track/account memory usage to the program.

There isn't built-in support for custom storage implementations. However, I've made a small change to make it easier to modify in the code and build yourself.

Storage appears as an interface to the client:
https://github.com/cenkalti/rain/blob/master/internal/storage/storage.go

If you are willing to write some code, this line is where you should start:

rain/torrent/session.go

Lines 448 to 450 in e8a4831

	func (s *Session) newStorage(id string) (storage.Storage, error) {
	return filestorage.New(s.getDataDir(id), s.config.FilePermissions)
	}

Please let me know if you have questions.

This issue is stale because it has been open for 30 days with no activity.

@cenkalti This is cool. Do you think newStorage could be exposed as a callback on Config? Then it would be easy for me to implement the interface without having to fork the code.

I added:

rain/torrent/config.go

Lines 205 to 206 in f14dfc0

	// Replace default storage provider
	CustomStorage storage.Provider `yaml:"-"`

Does that work for you?

This looks great, thanks!
