Configured-logger-file-set-auto-flush

Update the auto-flush policy used by a ConfiguredLogger file sink. This helper changes runtime durability behavior without rebuilding the logger.

Interface

pub fn ConfiguredLogger::file_set_auto_flush(self : ConfiguredLogger, enabled : Bool) -> Bool {}

input

• self : ConfiguredLogger - Config-driven runtime logger whose auto-flush policy should change.
• enabled : Bool - New auto-flush setting.

output

• Bool - Whether the policy update was applied.

Explanation

Detailed rules explaining key parameters and behaviors

• File-backed sinks update their runtime auto-flush policy.
• Queued file sinks forward the update to the wrapped file sink.
• Non-file sinks return false.
• This helper changes policy only; it does not itself flush pending data.

How to Use

Here are some specific examples provided.

When Need Runtime Durability Tuning

When a file sink should start flushing each write automatically:

ignore(logger.file_set_auto_flush(true))

In this example, runtime policy is updated without rebuilding the configured logger.

When Need To Relax Flush Pressure

When a file sink should stop auto-flushing for throughput reasons:

let ok = logger.file_set_auto_flush(false)

In this example, the call site updates policy explicitly and can inspect the result.

Error Case

e.g.:

• If the configured sink is not file-backed, the method returns false.

• If callers need an immediate flush action, file_flush() is the operational API.

Notes

1. Use this helper for runtime durability tuning.

2. Pair it with file_auto_flush() to verify the active policy.
