Configured-logger-close
Close the sink behind a ConfiguredLogger. This helper is the configured logger wrapper over RuntimeSink::close(...) for config-driven runtime teardown.
Interface
pub fn ConfiguredLogger::close(self : ConfiguredLogger) -> Bool {}
input
self : ConfiguredLogger- Config-driven runtime logger whose sink should be closed.
output
Bool- Whether the wrappedRuntimeSink::close(...)call reported a successful close action.
Explanation
Detailed rules explaining key parameters and behaviors
- This helper delegates directly to
self.sink.close(). - Plain file sinks forward to
FileSink::close()throughRuntimeSink. - Queue-backed file sinks close the wrapped file sink instead of only the queue wrapper.
- Generic
close()on queued file sinks does not drain pending queue entries first; it closes the wrapped file sink directly. - Console-style sinks and queue-wrapped console-style sinks return
trueas a no-op success because they do not expose a meaningful close step here. - For file-backed configured loggers, later
close()calls returnfalseafter the wrapped file handle has already been cleared.
How to Use
Here are some specific examples provided.
When Need Config-driven Runtime Teardown
When a config-built logger should release its sink resources:
ignore(logger.close())
In this example, sink teardown happens through the configured logger facade.
When Need To Observe Close Outcome
When application code wants a success flag from runtime close behavior:
let closed = logger.close()
In this example, callers can branch on the reported close result.
Error Case
e.g.:
-
If the configured runtime sink shape has no real close action, the helper may still return
trueas a no-op success. -
If the configured logger shares the same wrapped runtime sink state with another facade and one path already closed that file-backed sink, a later close attempt returns
false. -
If callers need a file-specific close path with queue flush nuances,
file_close()may be the better API.
Notes
-
This is the generic configured runtime close helper.
-
Prefer
file_close()when the configured sink shape is file-backed and queued records should be flushed before teardown. -
Converting the same configured logger through wrapper paths such as library projection still shares the wrapped runtime sink state, so close effects are visible across those facades.
