function::panic - Linux


function::panic handles errors in Linux as exceptions in Rust. It prints an error message and exits the program with an error code of 1.


function::panic(<error message>)
  • <error message>: A string slice specifying the error message.


There are no options or flags available.


Example 1:

use function::panic;

fn main() {
    // Create an error message
    let error_message = "An error occurred";
    // Call panic!() to handle the error and exit the program

Example 2:

use function::panic;

fn main() {
    // Call panic!() without an error message (defaults to "assertion failed!")

Common Issues

1. Exiting the program immediately:

  • Solution: Use the println!() function to print the error message instead of panic!().

2. Unknown errors:

  • Solution: Ensure proper error handling and provide meaningful error messages.


function::panic can be integrated with other Rust code using the panic!() macro. This macro uses function::panic to handle errors.
