unable to compile with rust nightly or rust stable

hi! I am trying to build the main branch and end up with the following error when compiling with either rustc 1.44.1 or rust nightly. I wonder if I am doing something silly? The gitlab CI tests seem to be working fine, so I must be ;-).

$ cargo build --all-features
...
