[die] is a simple Rust library to make it easy to handle errors and exit in command line programs.
```toml
[dependencies] die = "0.2" ```
Example usage:
``rust
use die::Die;
// Result:
Ok(1).die("no number"); // unwraps to 1 successfully
Err("failure").die("strange error"); // printsstrange error` to stderr then exits with code 1
// Option:
Some(1).die("no number"); // unwraps to 1 successfully
None.die("none option"); // prints none option to stderr then exits with code 1
// custom error codes:
Err("failure").diecode("strange error", 4); // prints strange error to stderr then exits with code 4
None.diecode("none option", 5); // prints none option to stderr then exits with code 5
// die! macro:
die!("argument to -e must be numeric"); // prints message to stderr then exits with code 1
die!(2; "argument to -e must be numeric"); // prints message to stderr then exits with code 2
die!("argument to -e must be numeric"; 3); // prints message to stderr then exits with code 3
die!("argument {} must be {}", "-e", 1; 4); // prints argument -e must be 1 to stderr then exits with code 4
die!("argument {} must be {}", "-e", 1); // prints argument -e must be 1 to stderr then exits with code 1
die!(2); // prints nothing, only exits with code 3
die!(); // prints nothing, only exits with code 1
