Singleflight with Generics!

Package singleflight provides a duplicate function call suppression mechanism.

A type-safe wrapper around golang.org/x/sync/singleflight that adds generic type support.

• No more type assertions needed in your code:
  • Group[K ~string, V any] - A type-safe version of the original Group.
  • Result[V any] - A generic version of the Result type.
• 100% compatible with the original package, maintaining identical behavior.

For usage examples, see examples_test.go.

Updates & Versioning

• This package will be kept in sync with the original golang.org/x/sync/singleflight package until it adds native generic support.
• Version tags will align with the original package's versioning.
• If you notice an update before I do, please open an issue or submit a pull request.
