fl::ScopedLogDisable Class Reference

Detailed Description

RAII class to temporarily disable all logging output.

Creates a scope where all fl::print/flprintln output is suppressed. When the object is destroyed, the previous log level is restored.

Usage:

void runValidation() {
    {
        fl::ScopedLogDisable guard;  // Suppress logging
        // ... validation code (FL_DBG, FL_WARN, fl::println suppressed) ...
    }  // Logging restored when guard goes out of scope
 
    // Or with fl::optional for manual control:
    fl::optional<fl::ScopedLogDisable> guard;
    guard.emplace();  // Disable logging
    // ... work ...
    guard.reset();    // Re-enable logging
    Serial.println("JSON result");  // Raw Serial.print bypasses fl:: logging
}
