Package singleflight provides a duplicate function call suppression mechanism.

This fork adds generics support (Group[K comparable, V any] and Result[V any]) to the original x/sync/singleflight package.

• I will keep this package up-to-date with the original one, at least until x/sync/singleflight adds support for generics. If you notice an update before I do, please open an issue or submit a pull request.
• Versions will be tagged to align with the same versioning as the x/sync/singleflight package.

For example usage, see:

• Group.Do
• Group.DoChan
• Group.DoForget
