Macro cmd_lib_macros::cmd_die [−][src]
cmd_die!() { /* proc-macro */ }
Report fatal errors and exit process conveniently
e.g:
let file = "bad_file"; cmd_die!("could not open file: $file"); // output: // FATAL: could not open file: bad_file
format should be string literals, and variable interpolation is supported. 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.
