Assert exact same dependencies as original lockfile--offline
Don't access network--frozen
Equivalent to --locked and --offline-v, --verbose
Verbose output (use twice for very verbose)-q, --quiet

BEHAVIOR
Creates new Cargo.lock if none exists. Rebuilds existing lockfile with newest compatible versions. Use cargo update for more control over version updates.
INSTALL
sudo apt install cargo
sudo dnf install cargo
sudo apk add cargo
sudo zypper install cargo
nix profile install nixpkgs#cargo
