Crate gossan_engine 

gossan-engine

High-performance stateless SYN scanner and banner grabber.

Replaces gossan-synscan with an architecture designed to beat masscan:

• Stateless SYN scanning via netforge::SeqEncoder (zero per-connection state)
• Randomized scan order via schedule::BlackrockPermutation (IDS evasion)
• Batch packet I/O via netforge::PacketEngine (sendmmsg / AF_XDP)
• Lock-free result pipeline via crossbeam SPSC channels
• Token-bucket rate control with sub-microsecond precision

Usage as a Gossan Scanner

use gossan_engine::EngineScanner;
let scanner = EngineScanner::default();
scanner.run(input, &config).await?;
