To avoid having to handle the failure case of printing to standard output, you can use alternate functions: the functions in std.log for documentation will use the latter option to print to standard error (stderr) and silently return on failure. The next code sample, hello_again.zig demonstrates the use of std.debug.print. hello again.zig array bounds checking.

typically do not expect writing text to the standard output to fail. To avoid having to handle the failure case of printing to standard output, you can use alternate functions: the functions in std.log for documentation will use the latter option to print to standard error (stderr) and silently return on failure. The next code sample, hello_again.zig demonstrates the use of std.debug.print. hello_again.zig verifies its argument is true. // It will return an error if its argument is false to indicate a failure. // 'try' is used to return an error to the test runner to notify it that the test
