pub fn init_logging(config: &LoggingConfig) -> Result<LoggingRuntime>Expand description
Installs process-wide operational logging from resolved config.
Stderr is always enabled. Explicit file sinks fail startup if they cannot be opened.
Verbosity comes from LoggingConfig::level: records below that minimum severity are discarded.
Dropping the returned LoggingRuntime flushes sinks and detaches this logger from the
process-global log proxy when it is still installed.
