function::panic - Linux

Overview

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.

Syntax

function::panic(<error message>)

• <error message>: A string slice specifying the error message.

Options/Flags

There are no options or flags available.

Examples

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
    panic!(error_message);
}

Example 2:

use function::panic;

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

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.

Integration

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