What does that sort.Find do that is new ? Does it just give index number between 0 and N and generate those index by binary searching ? That’s IMO really weird interface ? Why not take a slice and a comparison closure taking one or two Ts and keeping the way the indexing works private ?
Sure, those are the APIs I would expect. So I don’t understand what the sort.Find does that is “new” ? (except presenting a definitely weird interface to its user)
It’s the “new” part of the statement I don’t understand. (and to a lesser degree, the interface design)
It’s not “new” in that sense. Rob Pike just felt like sort.Search was too awkward, so he proposed a new function that’s maybe 10% less awkward. It’s the same functionality either way.
I yearn for the day when Go removes all mentions of sort.Interface lol. Thanks for work BTW.
I actually always really appreciated the cleverness of sort.Interface. It really showed what the language designers were going for.
What were they going for?
They were, as far as I can tell, trying to show the power of nominative types combined with interfaces.
They finally fixed the ballast thing!
I plan to continue to allocate an extra 100MB slab, for luck.

Does that do what you want?

You can use it for things other than slices. For example, you could use it to implement something like git-bisect
