Function log::set_logger_racy

pub unsafe fn set_logger_racy(
    logger: &'static dyn Log,
) -> Result<(), SetLoggerError>

A thread-unsafe version of set_logger.

This function is available on all platforms, even those that do not have support for atomics that is needed by set_logger.

In almost all cases, set_logger should be preferred.

Safety

This function is only safe to call when no other logger initialization function is called while this function still executes.

This can be upheld by (for example) making sure that there are no other threads, and (on embedded) that interrupts are disabled.

It is safe to use other logging functions while this function runs (including all logging macros).
