hello-sayer

A Rust library for generating and printing Hello world messages.

Usage

Install the library with:

cargo add hello-sayer

The following functions are included:

• generate_hello_message() -> &'static str - Returns "Hello world!" as a string slice
• say_hello() -> () - Prints the string returned by generate_hello_message
• say_hello_string(&str string) -> () - Prints the string slice given.
• say_hello_handler(fn() -> &'static str) -> () - Prints the string slice returned by the given handler.

Is this useless?

Yes. You can achieve the same functionality by just using the println! macro.
