generic VS async

You might also consider using other data structures instead of slices, for example, a linked list can be grown without an issue.

I recently saw a go generic data structures library in the wild: https://github.com/zyedidia/generic.

Anyone have any more? I'm curious what people come up with for goroutines/channels.

// Taken from: https://github.com/nkcmr/async/blob/main/async.go type syncPromise[T any] struct { done chan struct{} v T err error } func (s *syncPromise[T]) Await(ctx context.Context) (T, error) { select { case <-ctx.Done(): var zerov T return zerov, ctx.Err() case <-s.done: return s.v, s.err } } func (s *syncPromise[T]) Settled() bool { select { case <-s.done: return true default: return false } }

I made this: https://github.com/nkcmr/async so I can experiment with the idea of Promises in Go. Keep in mind it's experimental and I've only lightly played around with the pattern.
