[dependencies]
patternscanner = "0.4.0"

Example

// Use the multithreaded pattern scanners
use patternscanner::mt::{pattern_scan, pattern_scan_all};

// Scan for a single match of the pattern
let result = pattern_scan(
    &[0x00, 0x01, 0x02, 0x33, 0x35, 0x33, 0x42, 0x07, 0x08, 0x09],
    "33 35",
).unwrap();
assert_eq!(result, Some(3));

// Scan for a single match of the pattern with a wildcard
let result = pattern_scan(
    &[0x00, 0x01, 0x02, 0x33, 0x35, 0x42, 0x33, 0x35, 0x69, 0x09],
    "33 ? 42",
).unwrap();
assert_eq!(result, Some(3));

// Scan for all matches of the pattern with a wildcard
let result = pattern_scan_all(
    &[0x00, 0x01, 0x02, 0x33, 0x35, 0x42, 0x33, 0x35, 0x69, 0x09],
    "33 35 ?",
).unwrap();
assert_eq!(result, [3, 6]);
