    The `dev` [unoptimized + debuginfo] profile target(s) completed in 0.09s
warning: the following packages contain code that will be rejected by a future version of Rust: imap-proto v0.10.2
Note: to find out what the problems were, use the `--future-incompat-report` option, or run the `cargo report future-incompatibilities --id 1` command.
