Detailed Description

This file provides an alternative way to log messages without using macros, offering cleaner code in some scenarios at the cost of some performance.

The macro-free mode is implemented using __builtin_FILE(), __builtin_FUNCTION(), __builtin_LINE() which may vary by compiler:

While convenient, the macro-free approach has several performance implications compared to macros:

Higher Latency: Format metadata isn't available at compile time, requiring additional runtime copying of metadata to the backend thread
Always-Evaluated Arguments: Unlike macros which skip evaluation for disabled log levels, arguments to these functions are always evaluated
No Compile-Time Removal: Cannot be completely compiled out with QUILL_COMPILE_ACTIVE_LOG_LEVEL_<LEVEL> as macros can
Backend Thread Impact: Slightly reduced throughput in the backend due to runtime metadata storage and processing

For performance-critical logging paths, use the macro-based logging interface. Tag structure for log messages that supports multiple tags
