TīmeklisFirstly, you'll need to add the crate into your Cargo.toml file as a dependency. This will retrieve the rand crate from crates.io. Next, add this to your crate root. As this example is going to provide a simple output through the terminal, we'll create a main function and print two randomly generated numbers to the console. TīmeklisThree different methods for generating random data are provided since the optimal implementation of each is dependent on the type of generator. There is no required relationship between the output of each; e.g. many implementations of fill_bytes consume a whole number of u32 or u64 values and drop any
