Configured-logger-file-reopen-append

Reopen the file sink behind a ConfiguredLogger in append mode. This helper is the explicit append-oriented recovery shortcut.

Interface

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

input

• self : ConfiguredLogger - Config-driven runtime logger whose file sink should be reopened in append mode.

output

• Bool - Whether reopen succeeded.

Explanation

Detailed rules explaining key parameters and behaviors

• Plain file sinks reopen in append mode through the wrapped RuntimeSink.
• Queued file sinks forward reopen behavior to the wrapped inner file sink.
• This helper is a specialized shortcut for a common reopen mode.
• Non-file sinks return false.

How to Use

Here are some specific examples provided.

When Need Append-preserving Recovery

When file logging should continue appending after a reopen:

ignore(logger.file_reopen_append())

In this example, reopen behavior is fixed to append mode.

When Want An Explicit Append Shortcut

When code should avoid manually setting append overrides:

let ok = logger.file_reopen_append()

In this example, the call site states append intent directly.

Error Case

e.g.:

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

• If callers need truncate behavior instead, file_reopen_truncate() is the correct API.

Notes

1. Use this helper for explicit append-mode reopen flows.

2. It is especially useful after transient file availability issues.
