Macro cmd_lib::die[−][src]

macro_rules! die {
    ($($arg:tt)*) => { ... };
}

Report fatal errors and exit process conveniently

The arguments format is the same as in println!() macro. Note that this macro is just for convenience. The process will exit with 1 and print “FATAL: …” messages to error console. If you want to exit with other code, you should probably define your own macro or functions.

let file = "bad_file";
die!("could not open file: {}", file);
// output:
// FATAL: could not open file: bad_file
