Tracking issue for slice_partition_at_index

[Mokosha]

This is the tracking bug for the discussion outlined in rust-lang/rfcs#1470.

I'm working on implementing this in the libstd, and will add it as an unstable feature pending resolution of any comments that may arise in this thread. I plan to add comprehensive testing as well.

Just for the record, if someone needs this functionality right now, the order_stat crate provides an implementation of the Floyd-Rivest selection algorithm.

A thought: since we have sort and sort_unstable, should the method that got implemented be partition_unstable_at_index instead? Though I suppose there's no good stable way to do it...

Hi @Mokosha , is this expected to be stabilized eventually?
