Configured-logger-file-clear-rotation

Disable runtime rotation on a ConfiguredLogger file sink. This helper is the direct shortcut for clearing rotation policy.

Interface

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

input

  • self : ConfiguredLogger - Config-driven runtime logger whose rotation policy should be cleared.

output

  • Bool - Whether the policy update was applied.

Explanation

Detailed rules explaining key parameters and behaviors

  • File-backed sinks clear their runtime rotation policy.
  • Queued file sinks forward the update to the wrapped file sink.
  • Non-file sinks return false.
  • This helper is equivalent in intent to setting rotation to None, but is clearer at the call site.

How to Use

Here are some specific examples provided.

When Need To Disable Rotation Explicitly

When runtime file rotation should be turned off:

ignore(logger.file_clear_rotation())

In this example, rotation policy is removed directly.

When Need A Clear Intent Shortcut

When code should make the disable-rotation intent obvious:

let ok = logger.file_clear_rotation()

In this example, the call site reads more clearly than a generic config setter.

Error Case

e.g.:

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

  • If callers need to switch to another rotation config rather than disable rotation, file_set_rotation(...) is the better API.

Notes

  1. Use this helper when the desired effect is simply “rotation off”.

  2. It is clearer than passing None through a broader setter when intent matters.
