Thanks for the change!

Can you also add export CARGO_HOME="${srcdir}/.cargo" to prepare() and build() so that rust does not clutter the home dir?

And actually, $pkgver now begins with beta, which is a version decrease. So you either need to increment $epoch or change the pkgver() logic.

Official version is 0.0.3, as rusty-keys --version reveals. That needs to be parsed from the source, if git tags are unreliable.
grep -E '^[[:space:]]*version[[:space:]]*=' Cargo.toml | awk -F= '{print $2}' | tr -d \"\'' ' does it for me.

pkgver() could look like:

pkgver() {
  cd "${srcdir}/rusty-keys"

  _ver="$(grep -E '^[[:space:]]*version[[:space:]]*=' Cargo.toml | awk -F= '{print $2}' | tr -d \"\'' ')"
  _rev="$(git rev-list --count HEAD)"
  _date="$(git log -1 --date=format:"%Y%m%d" --format="%ad")"
  _hash="$(git rev-parse --short HEAD)"

  if [ -z "${_ver}" ]; then
    error "Version could not be determined."
    return 1
  else
    printf '%s' "${_ver}.r${_rev}.${_date}.${_hash}"
  fi
}

(See also my package rusty-keys-nosystemd-git.)

Regards!

The compilation errors were due to upstream not providing Cargo.lock, this has been fixed.

I also put cargo fetch in prepare() so build() no longer downloads anything, thanks for the pointer.
