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:2:4The 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.
