Is there a way to use String::from with variables? I tried using it similarly to println!(), but doesn't seem to work.

String::from("[INFO]: {}", message) Expected: // Returns: "[INFO]: My info message here" Got: // Error: argument unexpected

    Sounds like you want to use format! Commented Oct 28, 2022 at 10:01

Rust doesn’t really practice variadic functions because we have big metaprogramming potential: modern generic system and about 6 types of macros.

In this case you need the format macro:

format!("[INFO]: {}", message)
