With this MR:
$ cargo run --example=size | cat Finished dev [unoptimized + debuginfo] target(s) in 0.75s Running `/home/pmo/Repos/rust-termion/target/debug/examples/size`Size is (135, 72)
Note that this will also allow the associated test to pass when stdout is not a tty.
Feedback is appreciated, I am not an expert on idiomatic Rust. Let me know if this is better rolled into a full refactor for any filedes.
