File-sink-reopen-with-current-policy

Reopen a FileSink using the currently stored runtime policy. This helper is useful when direct recovery should happen without supplying a one-off append override.

Interface

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

input

• self : FileSink - File sink that should be reopened with current policy.

output

• Bool - Whether reopen succeeded.

Explanation

Detailed rules explaining key parameters and behaviors

• This helper reuses the sink's currently stored append policy.
• It differs from reopen(...) because it does not accept a per-call append override.
• Existing handle state is handled through the underlying reopen(...) behavior.
• On failure, the sink remains unavailable and open_failures is updated by the reopen path.

How to Use

Here are some specific examples provided.

When Need Policy-preserving Recovery

When a file sink should be reopened without changing runtime append behavior:

ignore(sink.reopen_with_current_policy())

In this example, recovery reuses the runtime policy already stored on the sink.

When Separate Recovery From Policy Mutation

When append mode should be controlled elsewhere:

let ok = sink.reopen_with_current_policy()

In this example, reopen is explicit while policy mutation stays separate.

Error Case

e.g.:

• If callers want to change append behavior during reopen, reopen(...), reopen_append(), or reopen_truncate() are better APIs.

• This helper still depends on the underlying file backend being able to reopen the path successfully.

Notes

1. Use this helper when recovery should respect the currently stored runtime policy.

2. It is clearer than passing no override through a more general reopen API.
