Configured-logger-flush

Flush a ConfiguredLogger and return one compatibility count. This helper is still available for older code, but new configured-runtime code should prefer flush_progress() because it exposes queue advancement and plain-file fallback steps separately.

Interface

pub fn ConfiguredLogger::flush(self : ConfiguredLogger) -> Int {}

input

• self : ConfiguredLogger - Config-driven runtime logger whose sink should be flushed.

output

• Int - Compatibility count returned by the wrapped RuntimeSink::flush(...) call.

Explanation

Detailed rules explaining key parameters and behaviors

• This helper delegates directly to self.sink.flush().
• Under the hood, RuntimeSink::flush() now rebuilds one compatibility count from flush_progress().
• Queue-wrapped sinks still report queued-record consumption through that compatibility count.
• Plain file sinks still report the generic fallback flush step as 1 or 0.
• Plain console-style sinks still return 0.

How to Use

Here are some specific examples provided.

When Need Explicit Queue Progress

When older code already expects one numeric flush count from a config-built logger:

ignore(logger.flush())

In this example, the configured runtime logger is flushed without changing the legacy return shape.

When Need A Post-write Flush Barrier

When code only needs a coarse non-zero check and does not care which runtime dimension advanced:

let flushed = logger.flush()

In this example, callers still get one compatibility count rather than a structured progress snapshot.

Error Case

e.g.:

• If the configured runtime sink shape has no flushable state, the method may simply return 0.

• If callers need truthful generic progress semantics, flush_progress() is the better API.

• If callers need bounded manual draining rather than generic flush behavior, drain_progress(...) is usually the better API.

• If callers need file-specific success semantics on a file-backed logger, file_flush() is the better API.

Notes

1. Treat this method as a compatibility helper for older numeric code.

2. Prefer flush_progress() in new configured-runtime code.

3. The exact return value depends on which RuntimeSink variant the configured logger owns.
