This is simple tool which replaces all version wildcards (*) in your Cargo.toml with the newest version of the crate. It can also upgrade dependencies that already have versions.
To install, simply run:
cargo install cargo-stabilize
There are two primary ways to use it. Be warned: Using this tool will reformat your entire Cargo.toml and delete any comments therein. No non-comment information will be lost.
cargo stabilize will replace all * dependency versions with the newest version of that crate.cargo stabilize --upgrade will do the same thing, as well as upgrading the versions of all dependencies whose versions are not the newest.
