It looks like in 3.*.beta help() was deprecated in favor of about(), because they were looked as redundant, and somewhat similar to App::about().

But then they changed their minds and reverted that change before the 3.0 release, deleting instead about().

So, just use Arg::help() instead.

Same thing for long_help() and long_about().

Editions are separately chosen by each crate being compiled. The current revision of the ed25519 crate requires a compiler that supports the 2021 edition. (You can find this out through docs.rs's handy source view: https://docs.rs/crate/ed25519/1.4.0/source/Cargo.toml.orig)

If you're trying to compile Rust binaries using a fixed compiler version (or an older version that might be in your distro package manager), then it's important to include a Cargo.lock file in your project/container configuration. The lock file specifies exact versions of each crate, so that your build cannot be broken by new library versions requiring newer compiler features.

However, there's a catch: cargo install ignores the lock file by default. So, you'll also need to change your command to pass the --locked flag to cargo install.

(You should also consider using a newer Rust compiler version, so that you don't have to use old versions of libraries that may have known bugs.)

Using SFSymbols is only available from iOS 13, however some specific symbols can also have higher deployment version (14 or 15) Check your project version in your App Target "General" tab and minimum deployment of your desired symbol. If you want to use symbols for lower iOS you should mark creating image with if #available(iOS 13.0, *) as you mentioned. If you want to make fallback image for lower iOS , your only option is to create separate asset with UIImage(named: "heart.jpeg") . You can also export your symbols manually adding it to Assset catalogue, however keep in mind that you need to convert it from SVG format so some other format, because iOS lower than version 13 also does not support SVG preserving vector data.

This works

Note the splice so timeout will no longer take longer as the values turn 0

It looks like the executable is actually named x86_64-linux-gnu-gcc, see https://packages.debian.org/bullseye/arm64/gcc-x86-64-linux-gnu/filelist.

You are currently adding a keydown event listener to each audio tag. However, the audio tag is hidden, so you can't execute the keydown event on it. Thus, your code will not work.

Add the event listener to the document instead.

With a Clip one uses the methodstop() to halt the playback. A subsequently called start() will resume playback from the same point. But one can change the playback point to a new location with either the setFramePosition() or setMicrosecondPosition() methods.

With a SourceDataLine one can also use start() and stop() methods. But changing to a new playback point is limited and trickier. One can only move forward, and this is done by using the skip() method of the AudioInputStream that is used to obtain the data being output through the SourceDataLine.

If the sound you are playing is only meant to be played once through, I would tend to favor using the SourceDataLine. If you are going to play the sound over, repeatedly, and holding the data in memory is not a burden, then Clip would likely be the better choice.

With SourceDataLine you are not limited to using AudioInputStream as your source signal. You can also use a custom-made oscillator or synthesizer. Converting the output of the oscillator, if it is PCM, will have to be handled to match the audio format in that case.

Instead of takes_value(false) use min_values(0) (playground):
