Package: tailspin I intend to update rust-terminal-size in unstable to 0.3 soon (probablly a week or so).
Tailspin upstream already uses 0.3, and your Cargo.toml already allows 0.3, so this should be a simple matter of tweaking the Debian build-dependency. I've tested that the package builds with the build-depenency tweaked, if you want to do further testing the new version of terminal-size has been uploaded to experimental.
