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()orfile_runtime_state()is the better API.
Notes
-
Use this helper for direct runtime path visibility.
-
Empty string usually means the configured sink is not file-backed.
