Configured-logger-file-path

Read the effective file path used by a ConfiguredLogger. This helper is useful for diagnostics, support output, and confirming which file-backed runtime sink is active.

Interface

pub fn ConfiguredLogger::file_path(self : ConfiguredLogger) -> String {}

input

• self : ConfiguredLogger - Config-driven runtime logger whose file path should be inspected.

output

• String - Effective runtime file path, or an empty string for non-file sinks.

Explanation

Detailed rules explaining key parameters and behaviors

• File-backed sinks return their current file path.
• Queued file sinks forward the wrapped file sink path.
• Non-file sinks return an empty string.
• This helper is observation-only and does not modify file state.

How to Use

Here are some specific examples provided.

When Need Runtime Path Diagnostics

When diagnostics should show which file is active:

println(logger.file_path())

In this example, operators can verify the effective destination path directly.

When Build Support Output

When application state dumps should include file destination info:

let path = logger.file_path()

In this example, the path can be surfaced without reading broader runtime state.

Error Case

e.g.:

• If the configured sink is not file-backed, the method returns an empty string.

• If callers need richer file status than just the path, file_state() or file_runtime_state() is the better API.

Notes

1. Use this helper for direct runtime path visibility.

2. Empty string usually means the configured sink is not file-backed.
