Build fails

similar to issue #32 ? while installing on arch from the aur repos, i get this error:

error: custom inner attributes are unstable

warning: signal-backup-decode (bin "signal-backup-decode") generated 3 warnings
error: could not compile signal-backup-decode due to previous error; 3 warnings emitted

i am new to rust, and not so great a decoding compiler issues anyhow. but i believe the warnings are somewhat innocuous. it's the original error, the message about "unstable attributes" that is the problem, right? i followed the referenced link, but the info there is way beyond my understanding.

any thoughts on how to fix? trying to import my signal messages to sms on android so i can import to imessage...why be so difficult signal devs?!? lol

running rust 1.59.0

thanks,

As someone who also uses Arch, I personally don't like using Arch's built-in stuff for Rust. It looks like the AUR package isn't maintained by pajowu, so if you really want the AUR package to work, you'd have to talk to the AUR package maintainer about that.
The way that Rust is officially installed is with rustup, a script you run at https://rustup.rs. Once you run that script, you get cargo, the Rust package manager. From there, it's just cargo install signal-backup-decode and it works like a charm, at least on my machine ;)
