Configured-logger-file-rotation-enabled

Read whether rotation is currently enabled on a ConfiguredLogger file sink. This helper exposes whether runtime rotation policy is active.

Interface

pub fn ConfiguredLogger::file_rotation_enabled(self : ConfiguredLogger) -> Bool {}

input

• self : ConfiguredLogger - Config-driven runtime logger whose rotation state should be inspected.

output

• Bool - Whether rotation is currently enabled.

Explanation

Detailed rules explaining key parameters and behaviors

• File-backed sinks report whether a rotation config is active through the wrapped RuntimeSink.
• Queued file sinks forward the state from the wrapped inner file sink.
• Non-file sinks return false.
• This helper is narrower than file_rotation_config() when only a yes/no check is needed.

How to Use

Here are some specific examples provided.

When Need Runtime Rotation Visibility

When support output should expose whether rotation is active:

let rotating = logger.file_rotation_enabled()

In this example, callers get a direct boolean answer without inspecting config objects.

When Guard Rotation-specific Behavior

When logic should only run for rotating file sinks:

if logger.file_rotation_enabled() {
  println("rotation active")
}

In this example, runtime policy can drive control flow.

Error Case

e.g.:

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

• If callers need the actual rotation parameters, file_rotation_config() is the better API.

Notes

1. Use this helper for simple runtime rotation checks.

2. Pair it with file_rotation_config() when parameters also matter.
