Regarding Cargo.lock, the recommendation always was to include it in version control for application/binary crates, but not library ones. But tendencies changed over time to include it even for libraries. If a rust-toolchain file is tracked by version control, and is pinned to a specific stable release, then Cargo.lock should definitely be tracked too [1][2].

It’s strictly more information tracked, so there is no logical reason not to include it. There was this concern about people not being aware of --locked not being the default behaviour of cargo install, giving a false sense of security/reliability/reproducibility. But “false sense” is never a good technical argument in my book.

Anyway, your crate is an application/binary one. And if you were to not change the "*" dependency version requirement, then it is almost guaranteed that building your crate will break in the future without tracking Cargo.lock ;)

• Don’t use "*" dep version requirements.
• Add Cargo.lock to version control.
• Why read to string if you’re going to base64-encode and use Vec later anyway?

keep in mind that it’s hard to get real numbers on LDAC because decoding is proprietary

I used to think the same. But as it turns out, a decoder exists. Maybe some people don’t want anyone to know about it to keep the myths alive ;)

EDIT: Also, as a golden rule, whenever anyone sees the words High-Res in an audio context, they should immediately realize that they are being bullshitted.

Your information is a few years outdated. lineageOS neither comes rooted, nor does it offer a native way to root anymore. Magisk became a thing with a whole community around it. It’s an unlocked bootloader hider, root manager (and hider), and a system patcher, all wrapped up in one tool.

With Magisk, you give root access to the apps that need it, hide root ability from apps that require non-root devices (those apps do that by pretending to need root). Also, the Magisk app can rename itself, which is important as some apps check against the name itself.

The future challenge is with Google trying to force hardware identification (Apple style). I have not been following developments regarding that though, since as others mentioned, my X years old phone is still serving me perfectly, and I have no intention to upgrade any time soon.
