Status for armv7 vs. rust (and go)?

that for armv7:

QUOTE
I still have some little cute boards that I want to use from time to
time but the lack of proper porting of new language (like rust and iirc
go have problems too) is making new software unusable on those boards
(you can't even make some "smart speaker" for spotify as all the
spotify clients are in rust).

I was surprised. But, while I build rust for armv7, like for other
architectures, I do not having anything using it currently for
armv7.

I tried looking at "spotify" references via freshports. (Not that
I've any intent to use of spotify.)

rust dependent (latest then quarterly). . .

audio/spotify-player:
FreeBSD:13:armv7 0.10.0_3 0.10.0_2 (matching most other architectures)
FreeBSD:14:armv7 0.10.0_3 N/A      (matching most other architectures)

audio/spotify-qt (rust via audio/spotifyd):
FreeBSD:13:armv7 3.10 3.9 (matching most other architectures)
FreeBSD:14:armv7 3.10 N/A (matching most other architectures)

audio/spotifyd:
FreeBSD:13:armv7 0.3.3_15 0.3.3_14 (matching most other architectures)
FreeBSD:14:armv7 0.3.3_15 N/A      (matching most other architectures)

multimedia/librespot:
FreeBSD:13:armv7 0.4.2_8 0.4.2_7 (matching most other architectures)
FreeBSD:14:armv7 0.4.2_8 N/A     (matching most other architectures)

audio/spotify-tui:
FreeBSD:13:armv7 0.25.0_18 0.25.0_17 (matching most other architectures)
FreeBSD:14:armv7 0.25.0_18 N/A       (matching most other architectures)

audio/ncspot:
FreeBSD:13:armv7 0.13.0_2 0.13.0_1 (matching most other architectures)
FreeBSD:14:armv7 0.13.0_2 N/A      (matching most other architectures)


go dependent . . .

audio/visp-go (via lang/go120):
FreeBSD:13:armv7 g20210723_13 g20210723_13 (matching most other architectures)
FreeBSD:14:armv7 g20210723_13 N/A          (matching most other architectures)


May be things build but there are operational problems?

Anyway, I'd be interested to learn of whatever types of
armv7 problems rust may be currently having. (Rust being
a large build is a known issue.)
