error[E0599]: no method named `send` found for struct `futures_channel::mpsc::Sender<termion::event::Key>` in the current scope

[behnam]

With latest stable rustc/cargo:

~$ cargo --version
cargo 1.47.0 (f3c7e066a 2020-08-28)
~$ rustc --version
rustc 1.47.0 (18bf6b4f0 2020-10-07)

I get this error when compiling prodash as a dependency of crates-io-cli:

    = note: the method `send` exists but the following trait bounds were not satisfied:

            which is required by `futures_channel::mpsc::Sender<termion::event::Key>: futures_util::SinkExt<_>`
