rustHow to throw an error in Rust

Throwing an error in Rust is done using the panic! macro. This macro will cause the program to immediately exit with a message.

Example code

fn main() {
    panic!("Something went wrong!");
}

Output example

thread 'main' panicked at 'Something went wrong!', src/main.rs:2:4

The panic! macro takes a single argument, which is a string literal. This string will be printed to the console when the panic occurs.

The panic! macro is useful for signaling an unrecoverable error in the program. It should not be used for normal error handling.
