Compile time is good on rust 1.40.0 and bad on 1.41.0.
I guess related to rust-lang/rust#68666 rust-lang/rust#69671 .
Needs upstream fix

Use Flamegraph or hyperfine to measure building.
Likely, if your interface is not that essential, you can use (pico-args)[https://github.com/RazrFalcon/pico-args].
