This allows tools to enable rust logging without having to magically match rustc’s tracing crate version. In contrast to init_rustc_env_logger it allows you to choose the logger config directly rather than having to set an environment variable.
init_logger_with_additional_layer
This allows tools to enable rust logging without having to magically match rustc’s tracing crate version. In contrast to init_rustc_env_logger, it allows you to choose the logger config directly rather than having to set an environment variable. Moreover, in contrast to init_logger, it allows you to add a custom tracing layer via build_subscriber, for example || Registry::default().with(custom_layer).

Install our usual ctrlc handler, which sets rustc_const_eval::CTRL_C_RECEIVED. Making this handler optional lets tools can install a different handler, if they wish.
Installs a panic hook that will print the ICE message on unexpected panics.
This is the primary entry point for rustc.
