Runtime-sink-file-policy-matches-default

Read whether the current runtime file policy still matches the default policy of a RuntimeSink. This helper is useful for detecting operational drift on direct sink values.

Interface

pub fn RuntimeSink::file_policy_matches_default(self : RuntimeSink) -> Bool {

input

• self : RuntimeSink - Runtime sink whose runtime policy drift should be checked.

output

• Bool - Whether the current runtime file policy still matches the default.

Explanation

Detailed rules explaining key parameters and behaviors

• Plain File runtime variants compare current runtime file policy against their stored defaults.
• QueuedFile runtime variants forward the comparison from the wrapped inner FileSink.
• Non-file runtime variants return false.
• This helper is a compact drift signal when callers do not need to compare full policy objects directly.

How to Use

Here are some specific examples provided.

When Need Drift Detection

When diagnostics should report whether file policy changed after startup:

let unchanged = sink.file_policy_matches_default()

In this example, the runtime sink exposes whether runtime file policy still matches the baseline.

When Gate Reset Logic

When code should only reset policy if drift exists:

if !sink.file_policy_matches_default() {
  ignore(sink.file_reset_policy())
}

In this example, policy reset only happens when runtime state diverged from defaults.

Error Case

e.g.:

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

• If callers need the exact differences instead of a boolean drift signal, they should inspect both file_policy() and file_default_policy().

Notes

1. Use this helper for compact runtime policy drift checks.

2. It is especially useful before calling reset-style operations.
