Is there a Rust way to check if the STDIN buffer is empty before attempting to read it?

Question

I want my application to be able to read the input from a redirected file stream through source > my_app, but I do not want it to ask for user input in case there is no redirection.

C provides such methods (Checking the stdin buffer if it's empty) but I could not find any solution for Rust.

Answer 1

As trentcl suggested, the way to do it is atty crate.
