Description:
 librust-futures-util-dev - Common utilities and extension traits for the futures-rs library
Changes:
 rust-futures-util (0.3.17-3) unstable; urgency=medium
 .
   * Team upload.
   * Package futures-util 0.3.17 from crates.io using debcargo 2.4.4
   * Remove optional (in the rust sense) dependencies on old version of tokio to
     make the package instalable. (the "io-compat" feature that used them was
     already removed).
