File-sink-rotation-enabled

Read whether a FileSink currently has rotation configured. This helper is the quickest direct check for whether size-based file rotation is active on the sink.

Interface

pub fn FileSink::rotation_enabled(self : FileSink) -> Bool {

input

• self : FileSink - File sink whose current rotation setting should be inspected.

output

• Bool - Whether the sink currently has a Some(FileRotation) policy.

Explanation

Detailed rules explaining key parameters and behaviors

• This method reports whether self.rotation is currently set.
• It is a lightweight boolean companion to rotation_config().
• The result describes current policy state, not whether a rotation just happened successfully.
• This helper does not mutate sink state.

How to Use

Here are some specific examples provided.

When Need A Simple Rotation-policy Check

When diagnostics should show whether direct file rotation is enabled:

let enabled = sink.rotation_enabled()

In this example, callers can branch on whether rotation policy is currently present.

When Validate Rotation Policy Changes

When code should confirm that a policy update took effect:

sink.set_rotation(Some(file_rotation(1024, max_backups=3)))
ignore(sink.rotation_enabled())

In this example, the boolean result reflects whether the sink now carries rotation config.

Error Case

e.g.:

• If callers need the actual FileRotation value, rotation_config() is the better API.

• This helper does not report past rotation failures; use rotation_failures() or state() for that.

Notes

1. Use this helper for quick rotation-policy visibility.

2. It is a lighter-weight companion to reading the full rotation config.
