Rust port of evhz program - https://github.com/ian-kelling/evhz
Made as a simple Rust language exercise by the repo owner and to test out the Cargo ecosystem.
To compile the binary simply execute at the root prooject directory:
cargo build --release
Followed by executing the binary itself:
sudo ./target/release/revhz
Note that the binary has to be run as a superuser to get refresh rates, in the same fashion as the original program.
