Configured-logger-file-flush
Flush the file sink behind a ConfiguredLogger. This helper is the file-specific runtime flush surface for config-built file loggers.
Interface
pub fn ConfiguredLogger::file_flush(self : ConfiguredLogger) -> Bool {}
input
self : ConfiguredLogger- Config-driven runtime logger whose file sink should be flushed.
output
Bool- Whether the underlying file flush succeeded.
Explanation
Detailed rules explaining key parameters and behaviors
- Plain file sinks forward directly to file flush behavior.
- Queued file sinks first flush queued records, then flush the wrapped file sink.
- Non-file sinks return
false. - This helper is narrower than generic
flush()because it targets file sink behavior specifically.
How to Use
Here are some specific examples provided.
When Need Explicit File Durability Steps
When a config-built file logger should flush to disk explicitly:
ignore(logger.file_flush())
In this example, the file-backed runtime sink is flushed directly through the configured logger.
When Need A File-specific Success Flag
When code should branch on the outcome of a file flush:
let ok = logger.file_flush()
In this example, callers can distinguish file flush success from a non-file sink shape.
Error Case
e.g.:
-
If the configured sink is not file-backed, the method returns
false. -
If callers want generic queue or sink advancement instead of file-specific behavior,
flush()is the broader API.
Notes
-
Prefer this helper when the configured sink is known to be file-backed.
-
Queued file sinks may perform both queue flush and file flush work here.
