This is a tracking issue for fn make_contiguous of VecDeque.
The feature gate for the issue is #![feature(deque_make_contiguous)].

About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also uses as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.

Are there any blockers for stabilization of this feature?

Don't think so, don't have the time to push this to stabilization myself though.

I can push this through if @jonas-schievink and @Dylan-DPC think that a stabilization PR is warranted?

You'll have to ask the libs team; you can find them on Zulip

Normally we wait for a few months to gain any feedback (though this is small) so i'd wait a bit to see if there are any concerns

@Dylan-DPC This landed back in April, so it's been three months — how long do you generally want the trial period to run for?

Just here to say that I also need this feature in my application.

Add feature for amortized resizes
aede305 
Keep in mind that since this is a feature, _all_ evmap instances get
amortized if _anything_ in the dependency graph enables the feature
(indexmap-rs/indexmap#137 (comment)).
This is unfortunate, but given that the alternative is forking evmap,
we'll go with the feature approach for now. Hopefully one day we'll have
a way to [avoid this](rust-lang/cargo#2980 (comment)).

Not landing this yet since it's nightly-only at the moment due to
certain methods [in
`atone`](https://github.com/jonhoo/atone/blob/45ae1e42deaaaaa9a919957ade49982a7ac4655b/src/lib.rs#L58).
Nightly-only will go away once
rust-lang/rust#70929 and
rust-lang/rust#74217 both stabilize. The first
one will land on next stable, but the second has some more time to go
first.
