Does YARA-X Support Fast Scan Mode or Alternative Early Stop Mechanisms?
I'm trying to implement scanning that stops after the first pattern match is found, similar to classic YARA's -f (fast scan) option. After reviewing the documentation, I cannot find this functionality in YARA-X's Rust API.
Current Understanding
Based on the official documentation at yara_x - Rust, the Scanner struct only provides:
scanner.scan_file(file_path)
Neither method appears to accept parameters for early termination or fast scanning.
Specific Questions
- Does YARA-X currently support any equivalent to classic YARA's fast scan mode?
- Are there any undocumented scanner configuration options for early termination?
- Is there a callback mechanism or alternative API that allows stopping scan on first match?
- If not available, are there plans to implement this functionality?
