debug macro

Output a debug message. This macro only compiled under debug build and does nothing in release build.

Notice: to see the debug output, you must turn on ckb_script debugging log in the CKB node configuration.

Example

debug!("hello world");
debug!("there is a universal error caused by {}", 42);
