Struct HsScanner 

pub struct HsScanner { /* private fields */ }

Compiled Hyperscan databases for all detector patterns, sharded across cores at compile time.

Thread-safe: every database is immutable after compilation and the scratch pools are Mutex-guarded. The public scan/lookup surface is unchanged from the single-database version - pattern_info/ pattern_count still index a single global pattern_map keyed by the HS pattern id, because each shard’s patterns carry their ORIGINAL global id, so a match from any shard maps back through the same table and the scan output is the union of all shards in original-byte space.

Examples

use keyhog_scanner::simd::backend::HsScanner;

let _scanner = HsScanner::compile(&[(0, 0, "demo_[A-Z0-9]{8}", false)])?;

Implementations

impl HsScanner

pub fn compile( patterns: &[(usize, usize, &str, bool)], ) -> Result<(Self, Vec<usize>), String>

Compile patterns into a Hyperscan database.

Examples

use keyhog_scanner::simd::backend::HsScanner;

let _scanner = HsScanner::compile(&[(0, 0, "demo_[A-Z0-9]{8}", false)])?;

pub fn scan(&self, text: &[u8]) -> Vec<(usize, usize, usize)>

Scan text and return (hs_pattern_id, match_start, match_end). Uses a scratch pool for thread-safety without per-call allocation.

Examples

use keyhog_scanner::simd::backend::HsScanner;

let (scanner, _) = HsScanner::compile(&[(0, 0, "demo_[A-Z0-9]{8}", false)])?;
let _matches = scanner.scan(b"demo_ABC12345");

pub fn pattern_info(&self, hs_id: usize) -> Option<(usize, usize, bool)>

Look up detector and pattern metadata for a Hyperscan pattern id.

Examples

use keyhog_scanner::simd::backend::HsScanner;

let (scanner, _) = HsScanner::compile(&[(0, 0, "demo_[A-Z0-9]{8}", false)])?;
assert!(scanner.pattern_info(0).is_some());

pub fn pattern_count(&self) -> usize

Return the number of patterns compiled into the SIMD database.

Examples

use keyhog_scanner::simd::backend::HsScanner;

let (scanner, _) = HsScanner::compile(&[(0, 0, "demo_[A-Z0-9]{8}", false)])?;
assert_eq!(scanner.pattern_count(), 1);
