void voyant_log_init_c

Initialize Voyant logging system from C/C++.

This function initializes the Rust logging system for use in C/C++ applications. It sets up logging to stderr with INFO level as default, but respects the RUST_LOG environment variable for custom configuration.

The logging system supports multiple levels:

• TRACE: Very detailed diagnostic information for fine-grained debugging
• DEBUG: Detailed diagnostic information
• INFO: General informational messages (default)
• WARN: Warning messages for potentially harmful situations
• ERROR: Error messages for failures

Note

This function should be called only once, typically during application startup. Calling it multiple times will cause the program to panic.

Environment Variables:

Set RUST_LOG environment variable to control logging:

• RUST_LOG=trace - Enable trace level logging (most verbose)
• RUST_LOG=debug - Enable debug level logging
• RUST_LOG=info - Enable info level logging (default)
• RUST_LOG=warn - Enable warning level logging only
• RUST_LOG=error - Enable error level logging only
• RUST_LOG=off - Disable all logging
