pub fn proc_macro_logger_default_setup()Expand description
Sets up a default logging arrangement for the proc_macro.
This function should be called once in every top level function of your proc_macro crate.
To use a custom logging setup take a look at the source code of this function.
When writing your own setup function, make sure to use a static SETUP_LOGGER: Once = Once::new(); to ensure that the setup is only done once.
