What version of Rust?

rustc --version

[mqu]

facing same error with docker build env based on debian stretch :

root@ede162c3d486:/app# rustc -V
rustc 1.24.1
root@ede162c3d486:/app# cat /etc/os-release  | grep PRETTY_NAME
PRETTY_NAME="Debian GNU/Linux 9 (stretch)"

[vi]

Either use rust 1.30+ for building current websocat;
or use websocat from tag v1.1.0, with supplied Cargo.lock for building with rust 1.24.

[mqu]

I have been able to build websocat with docker having latest rust version.
