Tracking issue for VecDeque Extras #27788

Gankra · 2015-08-13T01:37:30Z

This covers the deque_extras blanket feature, which should probably be sharded more in the future. It covers:

truncate
resize
as_slices
as_mut_slices
swap_back_remove
swap_front_remove

Some notes:

truncate and resize are strange because they aren't directional (they just truncate off the back). Need work.
as_slices and as_mut_slices seem good to go. A bit niche, but so is VecDeque. Maybe move the mut to the end. RFC'd and everything.
swap_back_remove and swap_front_remove also seem good to go. Maybe move the directional specifier to the end. RFC'd and everything.

The text was updated successfully, but these errors were encountered:

eefriedman · 2015-09-02T00:22:09Z

shrink_to_fit and insert are now also part of deque_extras.

sfackler · 2015-09-17T06:22:56Z

I think we can pretty easily stabilize as_slices and as_mut_slices. Not sure about the others.

alexcrichton · 2015-09-24T15:28:13Z

This issue is now entering its cycle-long FCP for stabilization in 1.5

Specifically the as_slices and as_mut_slices along swap_*_remove methods are being considered for stabilization. We are also considering renaming the swapping methods.

llogiq · 2015-10-21T04:40:13Z

@alexcrichton How should the swapping methods be named?

alexcrichton · 2015-10-21T16:17:19Z

@llogiq as mentioned in the issue description, the other candidate names would be swap_remove_back and swap_remove_front

alexcrichton · 2015-10-22T00:09:56Z

The libs team discussed this during triage today and the decision was to stabilize:

insert
shrink_to_fit
as_slices
as_mut_slices
swap_remove_front (renamed from swap_front_remove)
swap_remove_back (renamed from swap_back_remove)

Gankra · 2015-10-22T13:29:47Z

Oh, we forgot to discuss as_mut_slices vs as_slices_mut.

I think we should move muts to the back as much as possible, even if in this case we're making "mutable slices", it's still the _mut variant of as_slices.

alexcrichton · 2015-10-22T15:18:29Z

Hm I'm not sure I'd follow the same reasoning, in method names types like &mut [T] and *mut T are referred to as mut_slice and mut_ptr. We've always known about this with regards to the _mut-at-the-end convention, so I would feel that these methods are correctly named.

Gankra · 2015-10-22T15:27:14Z

Yeah I've been a bit ambivalent about that naming scheme, but I guess it's
a bit too late for that!

The only remaining unstable methods on VecDeque are truncate and resize. Nominating to stabilize.

@rfcbot fcp merge
