tracing_appender did not work as global?

[xuanwa]

hello, I suffered from a problem that tracing_append did not work as global.
I register a subscriber in log_init(), and then call log_init() in main function.

app.log get only one record(register done), but all log informantions print to the terminal.

Did I miss any details？thanks a lot.

You're currently dropping tracing_appender's _guard at the end of log_init. Instead, it must be returned from the log_init function to fn main (or whatever function lives as long as the program does), as dropping the guard will close the file writer. For additional details, see the documentation on WorkerGuard. Once you do that, you should see things logged to the file.
